Synchronous primary cancers of the endometrium and ovary： review of 43 cases

Objective： To investigate the clinical and pathological characteristics, treatment methods, and prognosis of synchronous primary cancer of the endometrium and ovary. Methods： The clinical data of 43 patients with synchronous primary cancer of endometrium and ovary were retrospectively reviewed. The survival was calculated by Kaplan-Meier method and compared using the log-rank test. Results： The median age of the patients at diagnosis was 49 years （range, 28-73 years）. The most common symptoms were abnormal vaginal bleeding （69.8%） and abdominal or pelvic pain （44.2%）. Pelvic masses were found in 39.5% of the patients and enlarged corpus in 27.9% at physic examination, while pelvic masses were found in 67.4% of the 43 patients （29 cases） and thickening or abnormal endometrium in 23.3% （10 cases） during ultrasound examination. Of 25 patients examined by CT/MRI, pelvic masses were found in 13 cases and enlarged uterus in 11 cases. All 15 patients who underwent endometrial biopsies were proven to have endometrioid carcinomas. Serum CA125 level was found to be elevated in 22 of the 34 examined cases （64.7%） with median value 500 U/mL （range, 39-3439 U/mL）. FIGO stages of endometrial carcinomas： IA 18 cases, IB 20 cases, IC 2 cases, and ⅡA 3 cases; Stages of ovarian carcinomas： IA 19 case, IB 4 cases, IC 7 cases, Ⅱ 4 cases, and ⅢC 9 cases. Twenty-four patients （55.8%） were in stage I both endometrial and ovarian carcinomas. Thirty-one patients underwent total hysterectomy plus bilateral salpingo-oophorectomy with omentectomy and appendectomy, meanwhile, 12 patients had pelvic lymph nodes dissection. Thirty-eight of the 43 patients （88.4%） had a pathologically proven endometrial adenocarcinomas. The predominant ovarian histologies were endometrioid or mixed tumors with endometrioid components （30/43, 69.8%）. Postoperatively, 26 patients （60.5%） received adjuvant chemotherapy alone, 12 had chemotherapy plus radiotherapy, only one patients had radiation alone and the remaining 4 cases received no adjuvant treatment. The 3-year and 5-year survival rates of the group were 87.4% and 71.1% respectively. The 3-year and 5-year survival rates of patients with endometrioid carcinoma at both endometrial and ovarian were higher than that of those with non-endometrioid or mixed histologic subtypes （93.8%, 82% vs 79.7%, 69%）. The 3-year and 5-year survival rates of patients with early stages disease were better than those of other patients （93.3%, 93.3% vs 69.7%, 36.7%）. Recurrence developed in 15 patients （34.9%）. It was showed by univariate analysis that lower CA125 level, early FIGO stage, and adjuvant chemotherapy plus radiotherapy significantly and positively affected the 5-year survival rate, while only early FIGO stage and chemotherapy plus radiotherapy were revealed by multivariate analysis as independent prognostic factors. Conclusion： Synchronous primary cancers of the endometdum and ovary were different from either the primary endometrial or ovarian cancer, while usually it can be detected in early stage with a good prognosis. The impact of the CA125 level on prognosis needs to be further studied. Surgery treatment alone may be enough for early stage patients. Chemotherapy plus radiotherapy may be necessary for advanced patients.

Synchronous primary duodenal papillary adenocarcinoma and gallbladder carcinoma:A case report and review of literature

BACKGROUND Synchronous primary cancers(SPCs) have become increasingly frequent over the past decade.However,the coexistence of duodenal papillary and gallbladder cancers is rare,and such cases have not been previously reported in the English literature.Here,we describe an SPC case with duodenal papilla and gallbladder cancers and its diagnosis and successful management.CASE SUMMARY A 68-year-old Chinese man was admitted to our hospital with the chief complaint of dyspepsia for the past month.Contrast-enhanced computed tomography of the abdomen performed at the local hospital revealed dilatation of the bile and pancreatic ducts and a space-occupying lesion in the duodenal papilla.Endoscopy revealed a tumor protruding from the duodenal papilla.Pathological findings for the biopsied tissue revealed tubular villous growth with moderate heterogeneous hyperplasia.Surgical treatment was selected.Macroscopic examination of this surgical specimen revealed a 2-cm papillary tumor and another tumor protruding by 0.5 cm in the gallbladder neck duct.Intraoperative rapid pathology identified adenocarcinoma in the gallbladder neck duct and tubular villous adenoma with high-grade intraepithelial neoplasia and local canceration in the duodenal papilla.After an uneventful postoperative recovery,the patient was discharged without complications.CONCLUSION It is essential for clinicians and pathologists to maintain a high degree of suspicion while evaluating such synchronous cancers.

Synchronous quintuple primary gastrointestinal tract malignancies: Case report

Multiple primary malignancy is defined as two or more malignancies detected in an individual person. In particular, synchronous quintuple primary malignancy is extremely rare. A 52-year-old male with anal pain and intermittent blood-tinged stool was diagnosed with malignancies in the stomach, jejunum, ascending colon, transverse colon and rectum. He underwent a subtotal gastrectomy, segmental resection of the jejunum and total protocolectomy with end ileostomy. The postoperative pathologic findings were moderate differentiated gastric adenocarcinoma (pT1bN0M0, pStageIA), combined adenocarcinoma and neuroendocrine carcinoma of the jejunum (pT3N0M0, pStageIIA), three mucinous adenocarcinoma of the ascending colon (pT3N0M0, pStageIIA), transverse colon (pT1N0M0, pStageI) and rectum (pT3N1aM0, pStageIIIB). The tumors did not lack MLH-1 and MSH-2 expression, as the markers (bat26, D5S346, bat25, D2S123) suggest MSI-H presence. Adjuvant chemoradiotherapy was started according to regimen, FOLFOX 4 for advanced rectal cancer. Six years post-operation, the patient is currently attending regular follow-ups without recurrence or metastasis.

Surgical Treatment and Prognosis of Synchronous Double Primary Lung Cancer： a Report of 31 Cases

OBJECTIVE The concept of double primary lung cancer （DPLC） has been generally accepted. Recently, an increasing incidence of synchronous DPLC has been reported, while the diagnostic standard and treatment strategies remain to be improved. This study was conducted to investigate effective surgical treatment and prognosis of synchronous DPLC. METHODS From January 1983 to April 2004, 31 patients with synchronous DPLC were operated in our department. Clinical data, such as surgical pattern, postoperative complications, and survival status, of all these patients were reviewed retrospectively. RESULTS The 31 patients with synchronous DPLC accounted for 0.67% of all the 4,649 patients operated for primary lung cancer in our department during the same period. Both tumors of the synchronous DPLC were resected with Iobectomy or pneumonectomy in 12 patients, while among the other 19 patients at least 1 tumor was treated with partial pulmonary resection. The postoperative morbidity was 29%（9/31）, including 1 case of respiratory insufficiency, 3 cases of atelectasis, 2 cases of atrial fibrillation, 1 case of haemoptysis, 1 case of pleural effusion, and 1 case of wound fat necrosis. No deaths occurred during the operations or within 30 days postoperatively. The postoperative 1 -, 3-, and 5-year survival rates were 52%, 29%, and 20%, respectively. CONCLUSION The incidence of synchronous DPLC is low. An aggressive and reasonable surgical approach can achieve a satisfactory outcome in patients with synchronous DPLC. The postoperative morbidity is low. Some patients might achieve long-term survival.

Synchronous endometrial and ovarian cancer: A case report

BACKGROUND Synchronous endometrial and ovarian cancer(SEOC)is a rare genital tract tumor.Precise diagnosis is crucial for the disease management since prognosis and overall survival differ substantially between metastatic endometrial cancer(EC)or OC.In this review we present 2 cases of women who were diagnosed with SEOC,and discuss the clinical characteristic of SEOC,diagnostic and molecular profiling issues.Next generation sequencing of 10 gene panel was performed on cancerous tissue and uterine lavage samples.CASE SUMMARY In our report patients with SEOC had endometroid type histology with early stage and low-grade histology for both EC and OC.They underwent surgical treatment and staging.Next-generation sequencing of 10 gene-panel identified CTNNB1,PIK3CA,and PTEN gene mutations in ovarian tissue in one case,while none of these genes were mutated in other case.Literature review in support to our data suggest a good prognosis for SEOC diagnosed at early stage.CONCLUSION Accurate diagnosis of SEOC is essential for disease management and gene mutation analysis can be helpful as a complementary diagnostic and prognostic tool.
