Clinical analysis of multiple primary gastrointestinal malignant tumors:A 10-year case review of a single-center

BACKGROUND Multiple primary malignant tumors(MPMTs)was first described by Billroth as early as 1889,with the first report published by Warren and Gates in 1932.Since then,numerous cases have been reported.A literature review of 1104269 patients with cancer revealed that the incidence of MPMTs ranged from 0.73 to 11.7%.In recent years,however,there has been a significant upward trend in the incidence of this phenomenon,which may be associated with many different factors,including the advancement of modern diagnostic procedures facilitating the examination and diagnosis of more MPMTs,increased exposure to chemotherapy and radiotherapy that exacerbate the risk of new malignant tumors in patients with cancer,and prolonged survival of patients with cancer allowing sufficient time for the development of new primary cancers.AIM To analyze the incidence,clinical features,treatment factors,prevalence,and prognosis of patients with MPMTs in the gastrointestinal tract treated in a single center.Additionally,we analyzed the different tumor combinations,time interval between the occurrence of tumors,and staging.METHODS This retrospective cohort study analyzed 8059 patients with pathologically confirmed gastrointestinal malignant tumors treated at the Gansu Province Hospital in Lanzhou,Gansu,China between June 2011 and June 2020.Of these,85 patients had MPMTs.The clinical features,treatment factors,prevalence,and prognosis of this latter cohort were analyzed.RESULTS The incidence of MPMTs in patients with gastrointestinal malignant tumors was 1.05%(85/8059),including 83 double primary malignant tumors and two triple primary malignant tumors of which 57(67.06%)were synchronous MPMTs(SMPMTs)and 28(32.94%)were metachronous MPMTs(MMPMTs).The most frequent associations were found between the rectum colon cancers within the SMPMT category and the gastric-colon cancers within the MMPMT category.For the MMPMTs,the median interval was 53 months.The overall 1-,3-and 5-year survival rates from diagnosis of the first primary cancer were 91.36%,65.41%,and 45.97%,respectively;those from diagnosis of the second primary cancer were 67.90%,29.90%,and 17.37%,respectively.CONCLUSION MPMTs in the gastrointestinal tract have a high incidence and poor prognosis.Thus,it is necessary to perform both gastroscopy and colonoscopy in patients with gastrointestinal tumors.Multidisciplinary comprehensive diagnosis and treatment may improve the diagnosis rate and treatment efficiency of MPMTs.

Primary Cardiac Tumors Operated on in Côte d’Ivoire: They Are Almost All Myxomas

Objective: Through this surgical series, we present the epidemiological and anatomical-clinical aspects and the surgical results concerning patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Materials and Method: This is a retrospective descriptive study covering the period of January 1982 to December 2022, based on the medical records of patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Results: Twenty-seven (27) patients underwent surgery for a primary cardiac tumor, including 14 women and 13 men with a mean age of 41.5 years (range 19 - 76 years). The main circumstances of discovery were exertional dyspnea, palpitation and syncope or pseudo-syncope. The main site was the septal wall of the left atrium. The diagnosis of myxoma was confirmed by pathological examination of the surgical specimen in 96.3% (n = 24) of the patients and it was a malignant large cell immunoblastic lymphoma of the myocardium in 3.7% (n = 1) of the patients. The mean largest diameter was 46.1 mm. The postoperative course was marked by an ischaemic stroke (n = 1);recurrence of a left atrial myxoma 5 years after the first tumor removal (n = 1). Two cases of death were noted, one due to the evolution of immunoblastic large cell lymphoma and the other due to an extracorporeal circulation accident. Conclusion: Almost all primary cardiac tumors operated on in Abidjan are myxomas. The circumstances of the discovery of these cardiac tumors are multiple and varied but dominated by exertional dyspnea, palpitation and syncope. Whatever their histological type, primary cardiac tumors are serious affections, in view of the haemodynamic and rhythmic disorders they cause.

Clinical Significance of Serum IL-18 and IL-18BP in Patients with Benign or Malignant Primary Liver Tumors

OBJECTIVE To study the relationship between the serumlevels of IL-18 and IL-18BP in the development and growth ofprimary liver cancer,benign liver tumors and liver cirrhosis and todetermine the value of serum IL-18 and IL-18BP in the diagnosisof primary liver cancer.METHODS The serum levels of IL-18 and IL-18BP in 36 patientswith primary hepatic carcinoma(PHC)were detected.Eighteenpatients were diagnosed with various benign liver tumors and 21patients with cirrhosis of liver(LC),determined by using an ELISAassay.The serum levels of AFP in 36 patients with primary livercancer were examined.The relationship among levels of serumIL-18,IL-18BP and AFP in the primary liver cancer was explored.RESULTS The sIL-18 levels in PHC were significantly lower thanin control group,the benign liver tumor group and the LC group.The sIL-18BP in PHC was significantly higher than that in controlgroup,benign liver tumor group and LC group(P<0.001).Therewas a close correlation between the levels of IL-18,IL-18BP andclinical stage in PHC:the later clinical stages had lower levels ofIL-18 and higher levels of IL-18BP while the earlier clinical stageshad higher levels of IL-18 and lower levels of IL-18BP.There was anegative correlation between serum levels of IL-18 and AFP in thePHC group(r = -0.7152,n=36,P<0.01),and there was a positivecorrelation between serum levels of IL-18 BP and AFP in thepatients with PHC(r=0.6315,n=36,P<0.01).The IL-18 and IL-18BP in the patients with various benign liver tumors or LC weresignificantly higher than those in control group.The differenceswere statistically significant(P<0.01).CONCLUSION Serum levels of IL-18 and IL-18BP can reflectthe immune function of patients with primary liver cancer,withvarious benign liver tumors or with LC and can also be indicativeof the clinic stage of primary liver cancer.It can be used to assistin making a diagnosis and in determining the clinical stage ofPHC.Detecting AFP concurrently can help make the diagnosis ofprimary liver cancer more precise.

Analysis of load status and management strategies of main caregivers of patients with malignant tumors of digestive tract

Caregiver load refers to the subjective and objective negative impact of caregivers in the care of patients,and excessive load will have a serious impact on patients and caregivers themselves and can reduce their quality of life.For the main caregivers,it not only needs to care for the patients in life and daily life,but also needs to pay the cost of treatment for the patients,coupled with the need to carry out their own original work,life,etc.excessive life pressure,economic pressure,work pressure,emotional pressure,etc.lead to heavy load of the main caregivers,which can easily cause caregivers to have different degrees of psychological problems,which will cause serious adverse effects on the caregivers themselves and cancer patients,not conducive to the construction of a harmonious family and society.This article analyzes the current situation of primary caregiver burden in patients with gastrointestinal malignant tumors,analyzes its influencing factors,and specifies specific treatment strategies.It is hoped to provide scientific guidance for later related research and application.

High incidence combination of multiple primary malignant tumors of the digestive system

BACKGROUND Clinical reports of multiple primary malignant tumors(MPMTs)in the digestive system are increasing.In China,although the survival rate of patients with MPMTs is increasing,the quality of life is very low.Many patients have reached the advanced stage when the second primary tumor is found,resulting in no early intervention and treatment.This is due to the misunderstanding of MPMTs by clinicians,who treat such tumors as metastases.Therefore,before a patient has a second primary tumor,doctors should understand some common combinations of digestive system MPMTs to provide clinical guidance to the patient.AIM To explore the high incidence combination of digestive system MPMTs under heterochronism and synchronization.METHODS A total of 1902 patients with MPMTs at Peking Union Medical College Hospital were analyzed retrospectively.They were divided into metachronous MPMT and synchronous MPMT groups,and then the high incidence combinations of the first primary cancer and the second primary cancer in metachronous cancer and synchronous cancer were sorted.Sex and age differences between metachronous and synchronous tumors were tested by the chi square test and t test,respectively.A P value<0.05 was considered as statistically significant,and SPSS version 26.0(SPSS Inc.,Chicago,Illinois,United States)was used for statistical analysis.RESULTS Among the 1902 patients with MPMTs confirmed by pathology,1811(95.2%)cases were secondary primary cancers,89(4.7%)cases were tertiary primary cancers,and 2(0.1%)cases were quaternary primary cancers.Most(88.2%)of the secondary primary cancers were identified as metachronous multiple primary cancers six months after diagnosis of the first primary cancer.The top ten most common MPMTs in the first primary cancer group ranged from high to low as follows:Breast cancer,thyroid cancer,nonuterine cancer,lung cancer,colon cancer,kidney cancer,uterine cancer,bladder cancer,rectal cancer,and gastric cancer.The highest incidence rate of the first primary cancer in male metachronous cancer was lung cancer(11.6%),the highest incidence rate of the second primary cancer was still lung cancer(24.9%),the highest incidence rate of the first primary cancer in female metachronous cancer was breast cancer(32.7%),and the highest incidence rate of the second primary cancer was lung cancer(20.8%).Among them,breast cancer,nonuterine cancer and uterine cancer were female-specific malignant tumor types,and thyroid cancer also accounted for 79.6%of female patients.The top five metachronous cancer combinations,independent of female-specific malignant tumor types and thyroid cancer,were colon cancer and lung cancer(26 cases),kidney cancer and lung cancer(25 cases),rectal cancer and lung cancer(20 cases),gastric cancer and lung cancer(17 cases),and bladder cancer and lung cancer(17 cases).The most common synchronous cancer combination was colon cancer and rectal cancer(15 cases).CONCLUSION Screening for lung cancer should be performed six months after the detection of colon cancer while rectal cancer screening should be performed within six months.

Conduction disorder and primary cardiac tumor: a fatal case of multiple lipomas of the right atrium

Cardiac primary tumors are uncommon with an estimated prevalence between 0.17%and 0.19%.[1,2]Cardiac lipoma are extremely rare representing only 10%?19%of primary cardiac tumors and only few are symptomatic,depending on their location within the heart.[3,4]They originate from the subendocardium(50%),subepicardium(25%)or myocardium(25%)and with different sizes and locations.[5]Few cases of sudden death due to primary cardiac tumors are reported in literature(0.0025%);in these cases,conductive and haemodinamic abnormalities have been indicated as the cause of death.

Rare neonatal malignant primary orbital tumors: Three case reports

BACKGROUND Aggressive malignant primary orbital tumors are extremely rare in newborns.The current cases further clarify the clinical features of malignant primary orbital tumors in neonates.CASE SUMMARY At the time of presentation at the Seventh Center of People’s Liberation Army General(PLAG)Hospital,the children were 1-,2-and 5-mo-old,respectively,and included 2 boys and 1 girl.All three cases had unilateral proptosis at birth,and underwent mass excision and histopathologic examination.A peripheral primary neuroectodermal tumor,an aggressive infantile fibromatosis and an embryonic rhabdomyosarcoma were diagnosed,respectively.The first case underwent routine chemotherapy following surgery but died within three months due to worsening condition as the tumor spread throughout the body.The other two children were treated by surgery,and at the follow-up visits 6 mo and 1 year after surgery,respectively,the wound was completed healed,and they had normal growth and development without radiotherapy or chemotherapy.A review of highly uncommon orbital tumors in newborns is also provided.CONCLUSION Malignant primary tumors should be considered in the presence of unilateral proptosis in newborns.

A Rare Case of a Primary Cardiac Tumor Presenting as Fatal Ventricular Tachycardia

Primary cardiac tumors are extremely uncommon.Here,we report the case of a patient with a primary left ventricular interstitial tumor presenting with hemodynamically unstable ventricular tachycardia.In response to hemodynamically unstable ventricular tachycardia,an implantable cardioverter-defibrillator was inserted.One month after defibrillator implantation,the patient developed episodes of high ventricular tachycardia that could not be effectively terminated by catheter radiofrequency ablation,thus further confirming that the ventricular tachycardia was induced by the left ventricular interstitial tumor.The patient is doing well on medical therapy to date.

Clinicopathological significance and prognostic value of claudin10 expression in primary malignant tumors of digestive system:A metaanalysis

Objective:To investigate the correlation between claudin10 expression and clinicopathological characteristics and prognosis of primary malignant tumors of digestive system.Methods:We searched the PubMed,Web of Science,Ovid MEDLINE,CNKI,CQVIP,and WanFang Data databases.The data between claudin10 expression and clinical characteristics as well as survival outcome were extracted.RevMan 5.3 and Stata 15.1 software were employed for metaanalysis.Results:A total of 6 studies containing 512 patients with primary malignant tumors of digestive system were analyzed.The analysis showed that high expression of claudin10 was more common in cancer tissue than in normal tissue[OR=3.22,95%CI(2.26,4.60),P<0.01],and was associated with increasing tumor size[OR=6.21,95%CI(2.44,15.83),P<0.01],high differentiation[OR=0.56,95%CI(0.32,0.99),P=0.05],positive lymph node metastasis[OR=3.41,95%CI(1.09,10.65),P=0.03].The expression of claudin10 was not associated with sex[OR=1.62,95%CI(0.91,2.90),P=0.10],age[OR=1.72,95%CI(0.97,3.07),P=0.06],distant metastasis[OR=4.51,95%CI(0.55,36.70),P=0.16],or prognosis[HR=1.99,95%CI(0.93,4.23),P=0.08].Conclusion:The expression of claudin10 is correlated with the clinicopathological features of primary malignant tumors of digestive system and is a potential tumor marker.

Clinicopathological Correlation of Primary Malignant Bone Tumors—An Observational Study

Background: Primary malignant tumors arising from bone are uncommon but important malignant neoplasms which account for 0.2% of all primary cancers in adults and approximately 5% of all childhood malignancies. Aim: No comprehensive surveillance data about primary malignant bone tumors is available from this region of West Bengal in the literature. An attempt is undertaken to correlate clinicopathological findings, both histological & cytological features of primary bone tumours. Method: This observational study of clinical presentation was corroborated with cytology and histopathology of 67 cases of primary malignant bone tumors in 2005-2007 in a tertiary health care centre. Results: Among the primary malignant tumors, 39 cases (58.20%) were male and 28 (41.80%) were female. Sixty one lesions (91%) were located in the long bones and 6 (9%) involving flat and short bones. Osteosarcomas are found to be the predominant primary malignant bone tumors (44.77%), followed by Ewing’s sarcomas (20.89%), chondrosarcomas (13.43%), high grade giant cell tumor, and plasmacytoma (5.97%). Predilection for male (M: F 2:1) found in both osteosarcoma and chondrosarcoma, but it was reverse in cases of Ewing’s sarcomas. Conclusion: Osteosarcoma is the most common around knee joint and chondrosarcoma is frequent in long bones in this region. We made an attempt to correlate FNAC findings with the histopathology and it was seen that overall sensitivity of FNAC of primary malignant bone tumors was 56.71%.

Effect of TACE combined with radiotherapy on the expression of serum tumor markers and malignant molecules in patients with primary large liver cancer

Objective:To investigate the effect of TACE combined with radiotherapy on the expression of serum tumor markers and malignant molecules in patients with primary large liver cancer.Methods:A total of 90 patients with primary large liver cancer who were treated in our hospital between September 2016 and September 2018 were retrospectively analyzed and divided into the control group(n=51)who received radiotherapy and the TACE group(n=39)who received TACE combined with radiotherapy.The expression levels of serum tumor markers,angiogenesis indexes and apoptosis molecules were compared between the two groups before and after treatment.Results:Before treatment,there were no statistically significant differences in the expression levels of serum tumor markers,angiogenesis indexes or apoptotic molecules between the two groups.After treatment,the serum levels of tumor markers AFP,AFu,CGT,CEA and CA19-9 in the TACE group were lower than those in the control group;the serum levels of angiogenesis indexes HGF,VEGF,MMP-9 and EGFR were lower than those in the control group;the serum levels of apoptosis molecules Bax,Caspase-4 and Caspase-10 were higher than those in the control group,while the levels of Bcl-2 and Survivin were lower than those in the control group.Conclusion:TACE on the basis of radiotherapy can further reduce the tumor malignancy in primary large liver cancer patients.

Frequency of Benign and Malignant Tumors in Localized Vitiligo in Comparison to Generalized and Universal Vitiligo

Background: Autoimmune diseases like pemphigus and systemic lupus erythematosus are protective against skin malignancies like basal cell carcinoma and squamous cell carcinoma. Objective: As vitiligo is an autoimmune diseases, the aim of the present work is to record the frequency of all benign and malignant skin tumors among patients with different severity of vitiligo and to be compared with the skin tumors in healthy control. Patients and Methods: This is a case series, descriptive study done in the Department of Dermatology—Baghdad Teaching Hospital, Baghdad, Iraq, during the period from May 2014-May 2015. History was taken from each patient with vitiligo regarding age, gender, duration, personal and family history of vitiligo and other autoimmune diseases such as diabetes mellitus, thyroid dysfunction, and alopecia areata. Patients were assessed for past and present history of photodermatosis and any skin cancers. Healthy control was considered. Results: Three hundred and fifty patients with vitiligo were included in this study: 50 patients with universal vitiligo, 100 patients with generalized vitiligo, and 200 patients with localized vitiligo as well as 500 subjects as a healthy control. The ages of all studied subjects ranged between 31 and 77 years. Twenty four(48%) patients with universal vitiligo were males and 26 (52%) were females;49(49%) patients with generalized vitiligo were males and 51(51%) were females;101(50.5%) patients with localized vitiligo were males and 99(49.5%) were females and 235(47%) of control were males and 265(53%) were females. All skin tumors were seen to be high in healthy subjects and lower or absent in patients with vitiligo. Also patients with mild vitiligo had a higher frequency of skin tumors including benign and malignant than patients with severe vitiligo especially in patients with universal vitiligo. In addition, no photosensitivity or actinic reticuloid was detected in patients with vitiligo. Conclusions: Vitiligo especially generalized and universal type as an autoimmune disease had a protective action against photodamage, photosensitivity and skin tumors whether benign or malignant.

Gastrointestinal stromal tumors and second primary malignancies before and after the introduction of imatinib mesylate

Gastrointestinal stromal tumor （GIST） is the most common mesenchymal malignancy of the gastrointestinal tract.GISTs may coexist with different types of cancer,either synchronous or metachronous （1）.Most GISTs develop in a sporadic fashion,but familial occurrence,such as neurofibromatosis and Carney-triad,has also been reported （2）.The overall frequency of second tumors in different series varied from 4.5% to 33%.The most frequent types of GIST-associated cancers were gastrointestinal carcinomas （47%）,lymphoma/leukemia （7%）,carcinomas of prostate （9%）,breast （7%）,kidney （6%）,lung （5%）,female genital tract （5%）,carcinoid tumors （3%）,soft tissue and bone sarcomas （3%）,malignant melanoma （2%） and seminoma （1%） （1,3-5）.

THE CLINICOPATHOLOGICAL AND PROGNOSTIC STUDY ON 42 CASES WITH CARDIAC TUMOR

Objective: To analyze the relation between the pathological changes and the clinical manifestations and the prognosis of cardiac tumors through the pathological study on 42 cases with cardiac tumor, in order to improve the knowledge of the tumors, to make early diagnosis and to raise the curative ratio.Materials and Methods: 42 confirmed cardiac tumors of our department were selected, among whick 41was surgical specimen and 1 was autopsy. The study was Pcrformed by using the common and special histochemical staining.Results: 41 is Primary and 1 is secondary which is a metastazed hepatocelular carcinoma. In the Primary ones,39 (95.1%) is benign, including myxoma, fibroma,rhabdomyoma and Pericardial cyst, while 2 (4. 9%) is malignant, including neuroleminafibrosarcoma and malignant mesothelioma. In the myxomas, female patients occupy 75%, 91.7% exists in the left atrium and every one has got a peduncle adbesive to the fossa ovalis or adjacency of the atrial septum.Conclusions: The results of the pathological and prognostic study sbowes cardiac tuinors are quite different from the tumors in other sites, i.e., cven benign ones could cause fatal hemodynamic disturbance. Hence early diagnosis and early operation are necessary and if in such instance, the Prognosis of inost of the benign oncs would be good. But the prognosis of the malignant tumors is worst. The myxomas are different from the organized thrombi in heart cavity. And also the criteria of diagnosis and differential diagnosis are discussed.

Malignant Tumors of Heart: A Review

Malignant cardiac tumors are rare and challenging entity. Experience in treating these aggressive and lethal tumors is minimal and management protocols are not well defined and have to rely on case reports, and personal experiences. Most effective therapy for primary cardiac malignancy is a complete surgical resection and the role of chemoradiotherapy is still evolving.

Malignant Peripheral Nerve Sheath Tumor of the Thigh Invading the Superficial Femoral Artery, with Necrotic Lung Metastases as Presenting Symptoms

A NF1 (neurofibromatosis 1) patient developed multiple necrotic lung metastases from a sciatic malignant peripheral nerve sheath tumor (MPNST) invading the superficial femoral artery. The first diagnosis was metastases of a non-small-cell adenocarcinoma because the right calf MPNST was not clinically noticeable ant that the chest/abdomen PET/CT did not include the region of the legs. When the MPNST was diagnosed, new histological analysis on the metastases changed the diagnosis to that of epithelioid undifferentiated sarcoma. The article deals with the sometimes-delayed diagnosis in those NF1 patients with large palpable masses and chronic pain pre-existing the malignant transformation, and discusses the difficulty of the biopsy of necrotic metastases.
