Parallel pathways:A chronicle of evolution in rectal and breast cancer surgery

In this editorial,we have analyzed the historical evolution of rectal and breast cancer surgery,focusing on the progressive reduction of demolitive approaches and the increasing use of more conservative strategies,accompanied by a growing emphasis on perioperative treatments aimed at enhancing surgical outcomes.All of these changes have been made possible due to an increased awareness and understanding of oncological diseases and improved perioperative treatments.

Magnetic resonance imaging findings of radiation-induced breast angiosarcoma:A case report

BACKGROUND Breast conservation surgery(BCS)with adjuvant radiotherapy has become a gold standard in the treatment of early-stage breast cancer,significantly reducing the risk of tumor recurrence.However,this treatment is associated with adverse effects,including the rare but aggressive radiation-induced angiosarcoma(RIAS).Despite its rarity and nonspecific initial presentation,RIAS presents a challenging diagnosis,emphasizing the importance of imaging techniques for early detection and accurate diagnosis.CASE SUMMARY We present a case of a 48-year-old post-menopausal woman who developed skin ecchymosis on the right breast seven years after receiving BCS and adjuvant radiotherapy for breast cancer.Initial mammography and ultrasound were inconclusive,showing post-treatment changes but failing to identify the underlying angiosarcoma.Contrast-enhanced breast magnetic resonance imaging(MRI)revealed diffuse skin thickening and nodularity with distinctive enhan-cement kinetics,leading to the diagnosis of RIAS.This case highlights the crucial role of MRI in diagnosing and determining the extent of RIAS,facilitating timely and appropriate surgical intervention.CONCLUSION Breast MRI is crucial for detecting RIAS,especially when mammography and ultrasound are inconclusive.

Surgical management of the diabetic foot:The current evidence

The prevalence of diabetes mellitus and its associated complications,particularly diabetic foot pathologies,poses significant healthcare challenges and economic burdens globally.This review synthesises current evidence on the surgical management of the diabetic foot,focusing on the interplay between neuropathy,ischemia,and infection that commonly culminates in ulcers,infections,and,in severe cases,amputations.The escalating incidence of diabetes mellitus underscores the urgency for effective management strategies,as diabetic foot complications are a leading cause of hospital admissions among diabetic patients,significantly impacting morbidity and mortality rates.This review explores the pathophysiological mechanisms underlying diabetic foot complications and further examines diabetic foot ulcers,infections,and skeletal pathologies such as Charcot arthropathy,emphasising the critical role of early diagnosis,comprehensive management strategies,and interdisciplinary care in mitigating adverse outcomes.In addressing surgical interventions,this review evaluates conservative surgeries,amputations,and reconstructive procedures,highlighting the importance of tailored approaches based on individual patient profiles and the specific characteristics of foot pathologies.The integration of advanced diagnostic tools,novel surgical techniques,and postoperative care,including offloading and infection control,are discussed in the context of optimising healing and preserving limb function.

Conservative laparoscopic surgery of adnex torsion for fertility preservation

Objectives:To evaluate the safety and efficacy of conservative laparoscopic surgery for adnexal torsion and the feasibility of secondary operation.Methods:This is a retrospective study that consists of 17 patients with clinically diagnosed adnexal torsion who have a desire for pregnancy in the future.We performed conservative laparoscopic adnexal detorsion operations from January 2014 to June 2016 in Sir Run Run Shaw Hospital.The collected data,including age,onset time,maximum diameter of adnexal lesion,local blood flow signal,torsion degree,and recovery of local blood supply after detorsions,were analyzed.The blood flow of the lesion side,the antral follicles development,the basal endocrine hormone levels and the menstrual cycle were examined one-month and three-month post operation.Future fertility was investigated postoperatively.Results:All cases had no obvious clinical postoperative complications.There were no significant changes on menstrual cycle and ovarian function during the follow-up period.Conclusions:Adnexal torsion in young patients should be carefully treated and fertility reservation should be thoroughly considered.The decision to remove adnexa needs careful consideration.Conservative laparoscopic surgery is safe and does not increase the occurrence of serious complications.There is a higher possibility of a long delay between surgery and onset necrosis,but this is not always the case.Even if there is adnex thromboembolic infarction it does not result in serious complications such as pulmonary infarction.Conservative laparoscopic surgery can be performed first unless the clinician is certain it is already necrotic.We should do our best to reserve patients’fertility as much as possible.If necessary,a secondary surgery can be performed.

Recurrent ovarian endometrioma after conservative surgery:A retrospective study

Objective:To study the prevalence and associated factors of recurrent ovarian endometrioma after ovarian cystectomy.Methods:This retrospective study analyzed 303 patients who underwent cystectomy for ovarian endometrioma and had at least a 2-year follow-up at Srinagarind Hospital from January 2013 to December 2018.The patients were divided into the recurrent and nonrecurrent groups according to the findings from postoperative transvaginal ultrasonography 6 months after undergoing surgery.Nineteen factors were collected for risk evaluation.The prevalence of recurrent ovarian endometrioma and its 95%confident interval(CI)were calculated.Univariate and multivariable logistic regression analyses were performed to determine the association between factors and recurrence.Results:Recurrent ovarian endometrioma occurred in 33%(95%CI 27.7%-38.3%)patients.The median duration of followup was 36 months.during the median follow-up period of 36 months.Preoperative history of parity,preoperative infertility history,endometriosis surgery,moderate to severe dysmenorrhea,dyspareunia,intraoperative stage 4 according to revised American Society for Reproductive Medicine classification,presence of adenomyosis,and postoperative pain relief were associated factors based on univariate analysis.In contrast,infertility[odds ratio(OR)2.22,95%CI 1.14-4.33],moderate to severe dysmenorrhea(OR 2.13,95%CI 1.09-4.15),and postoperative pelvic pain relief(OR 0.22,95%CI 0.12-0.42)were independently associated factors based on multivariable logistic regression analysis.Conclusions:In our setting,preoperative infertility history and moderate to severe dysmenorrhea were associated with a higher recurrent ovarian endometrioma risk.In contrast,postoperative pain relief was significantly associated with lower recurrence risk.

Breast Conserving Surgery: Has the Standard of Care Enhanced Outcomes for Patients?

Breast Conserving Surgery (BCS) is a rapidly emerging field increasingly adopted to facilitate breast conservation and preserve breast aesthetics. Since the publication of the Randomized Controlled Trials (RCTs) of Breast Conserving Surgery versus mastectomy in early breast cancer, the adoption of BCS for breast cancer patients’ surgical management has been comprehensive. A computerized bibliographic search was performed on PubMed/MEDLINE, Embase, Google Scholar and Cochrane library databases. This article aims to perform a thorough review of new data regarding invasive cancer and margins while evaluating patient outcomes related to BCS after neoadjuvant chemotherapy focusing on margins, imaging evaluation, the extent of resection, and local regional recurrence outcomes. The growth pattern and biopsy of Ductal Carcinoma In Situ (DCIS) differ from invasive cancer, impacting margins. It is essential to understand how the Society of Surgical Oncology (SSO) DCIS margin guideline has influenced practice. Early breast cancer surgical management should be unique to each patient, driven by evidence-based medicine, and focused on specific clinical, histological, and molecular characteristics of the tumor. Conclusion: The current management for early breast cancer should be tailored and evidence-based to each patient based on the clinical, histological and molecular characteristics of the tumor. Presumably, the standard of care in BCS has enhanced the outcomes for this patient population. This review made by peers will help surgeons to stay up to date with the current literature and help them manage breast cancer while improving multiple clinical parameters such as Disease-Free Survival (DFS), Recurrence-Free Survival (RFS) and most importantly Overall Survival (OS).

Concomitant Boost Radiotherapy after Conservative Breast Surgery in Early Breast Cancer

Background: Radiation therapy after breast conserving surgery is a standard part of treatment for invasive breast cancer. Based on radiobiological models, it was found that shorter radiation schedules offered the promise of equivalent local control to standard radiation therapy by giving larger doses per fraction in shorter period of time. Methods: This study included 36 female patients with operable invasive stage I-II breast cancer. These patients underwent microscopic wide local excision of the primary tumor and lymph node dissection. They received adjuvant radiotherapy. The radiation dose was 40 Gy total dose in 15 fractions for whole breast and additional dose of 9 Gy in three consecutive fractions was delivered to tumour cavity simultaneously. Results: Mean age was 52 years (range: 30 - 67);most patients were of stage II disease and Grade II was the most common one. Invasive ductal carcinoma was reported in 94.4% and 72.2% of patients were hormone receptor positive. After median follow-up of 52 months, all patients were alive and ipsilateral local recurrence was reported in 1 case only. Grade IV radiation toxicity was not observed;moist desquamation was the most common acute reaction (61%) with grade III in 5.5% followed by dry desquamation in 55.6% of grade I only. Grade I erythema was recorded in 41.7% and grade II in 11%. Fibrosis was the most frequent late reaction (44.3%) with grade II in 11% followed by telengectesia then pigmentation (41.7%, 33.3% respectively). Conclusion: The regimen used in this study appears promising with acceptable acute toxicities and convenient for our patients and has the advantage of economic use of radiation facilities. However, larger number of patients and longer period of follow-up are needed for further evaluation.

Two Modified Surgical Procedures for Treating Early Stage Breast Cancer in China

Conventional pedicled-flap based surgeries in treating breast cancer have their limitations. New surgical regimens are yet to be explored, which will follow the oncological principle of being “to- tal tumor free”, whilst fit into the unique characteristics of China＇s own medical system as well as pa- tients＇ demand. From 2007 to 2013, 143 patients with early stage breast cancer were included in the study, with the average age of 46.1 years. Fifty-three patients were subjected to modified breast con- serving surgery （MBCS）＋latissimus dorsi （LD） flap reconstruction, 41 to skin sparing mastectomy （SSM）＋implant＋LD flap reconstruction, 29 to MBCS＋distal transverse rectus abdominis myocutaneous （DTRAM） flap reconstruction, and 20 to SSM＋DTRAM flap reconstruction. The results showed that out of the 143 patients, there was no graft loss. Minor complications included 4 cases of fat liquefaction, and 6 cases of seratoma, which all resolved after conservative treatment. Five patients had visible protu- berance in the abdomen, but not leading to any gastrointestinal symptoms. The reconstructed breasts all presented good shape. 96.7% of the patients were satisfied with the outcome. The follow-up period var- ied from 6 months to 60 months, and only one patient died from tumor metastasis in the brain. No local recurrence occurred. It was concluded that these two modified pedicled-flap surgeries are readily practi- cal, and aesthetically satisfactory, with high applicability in China. They do not compromise the on- cological outcomes, but also are well-accepted by Chinese patients.

Current aspects of therapeutic reduction mammaplasty for immediate early breast cancer management: An update

Breast-conservation surgery(BCS) is established as a safe surgical treatment for most patients with early breast cancer. Recently, advances in oncoplastic techniques are capable of preserving the breast form and quality of life. Although most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Among technical options, therapeutic reduction mammaplasty(TRM) remains a useful procedure since the BCS defect can be repaired and the preoperative appearance can be improved, resulting in more proportional breasts. As a consequence of rich breast tissue vascularization, the greater part of reduction techniques have based their planning on preserving the pedicle of the nipple-areola complex after tumor removal. Reliable circulation and improvement of a conical shape to the breast are commonly described in TRM reconstructions. With an immediate approach, the surgical process is smooth since both procedures can be carried out in one operative setting. Additionally,it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reduces the incidence of margin involvement. Regardless of the fact that there is no consensus concerning the best TRM technique, the criteria is determined by the surgeon's experience, the extent/location of glandular tissue resection and the size of the defect in relation to the size of the remaining breast. The main advantages of the technique utilized should include reproducibility, low interference with the oncological treatment and long-term results. The success of the procedure depends on patient selection, coordinated planning and careful intra-operative management.

Significance of ipsilateral breast tumor recurrence after breast conserving treatment: role of surgical removal

Objective： To analyze the pattern over time （dynamics） of further recurrence and death after ipsilateral breast tumor recurrence （IBTR） in breast cancer patients undergoing breast conserving treatment （BCT）. Methods： A total of 338 evaluable patients experiencing IBTR were extracted from a database of 3,293 patients undergoing BCT. The hazard rates for recurrence and mortality throughout 10 years of follow-up after IBTR were assessed and were compared to the analogous estimates associated to the primary treatment. Results： In a time frame with the time origin at the surgical treatment for IBTR, the hazard rate for further recurrence displays a bimodal pattern （peaks at the second and at the sixth year）. Patients receiving mastectomy for IBTR reveal recurrence and mortality dynamics similar to that of node positive （N＋） patients receiving mastectomy as primary surgery, apart from the first two-three years, when IBTR patients do worse. If the patients with time to IBTR longer than 2.5 years are considered, differences disappear. Conclusions： The recurrence and mortality dynamics following IBTR surgical removal is similar to the corresponding dynamics following primary tumor removal. In particular, patients with time to IBTR in excess of 2.5 years behave like N＋ patients following primary tumor removal. Findings may be suitably explained by assuming that the surgical manoeuvre required by IBTR treatment is able to activate a sudden growing phase for tumor foci most of which, as suggested by the systemic model of breast cancer, would have reached the clinical level according to their own dynamics.

Latissimus Dorsi Mini-Flap as a Volume Replacement Technique after Partial Mastectomy for Breast Cancer in the Upper and Central Breast Quadrants: A Single Center Experience

Background: The latissimus dorsi (LD) muscle flap plays an essential role in breast reconstruction after partial mastectomy for cancer because of its stability and versatility. We evaluated both oncologic and aesthetic outcomes in addition to the related complications of this flap as an adjunct to breast conserving surgery in the management of breast cancer patients. Methods: All patients underwent a one-stage procedure with immediate reconstruction through two-steps operation;wider local excision utilizing oncoplastic principles and mini flap harvest & volume replacement. Results: The study included 34 cases with early breast cancer;30 patients had partial breast resection and defect refilling by LD mini-flap, three patients underwent mastectomy and one patient underwent extended LDF. The mean defect volume was (212.63 cm3 ± 59.57) cm3, while the mean flap volume was (218.27 cm3 ± 53.64 cm3). Patient self-evaluation of the cosmetic outcome was excellent in 20%, good in 60% and satisfactory in 20% of patients. Panel evaluation according to Harvard scale showed excellent in 36.7%, good in 36.7%, fair in 26.7% of patients. The median hospital stay was 4 days. The postoperative complications included wound gap in 4 patients (13.3%), postoperative donor site seroma in 16 patients (53.3%). No flap loss or necrosis, no affection on arm or shoulder mobility occurred. Lastly, no tumor recurrence till now. Conclusion: Latissimus dorsi mini-flap can achieve adequate cosmetic and oncologic outcomes with a low incidence of complications in patients with early stage (I/II) breast cancer and small to medium sized breasts.

Accelerated partial breast irradiation:Current evidence and future developments

Whole breast irradiation after breast-conserving surgery for early breast cancer has become one of the standard treatment modes for breast cancer and yields the same effect as radical surgery.Accelerated partial breast irradiation(APBI)as a substitute for whole breast irradiation for patients with early breast cancer is a hot spot in clinical research.APBI is characterised by simple high-dose local irradiation of the tumour bed in a short time,thus improving convenience for patients and saving costs.The implementation methods of APBI mainly include brachytherapy,external beam radiation therapy,and intraoperative radiotherapy.This review provides an overview of the clinical effects and adverse reactions of the main technologies of APBI and discusses the prospects for the future development of APBI.

Presence of extensive intraductal component in patients undergoing breast conservative surgery predicts presence of residual disease in subsequent completion mastectomy

Background Local recurrence remains a serious problem among patients undergoing breast conservative surgery. This study aimed at identifying risk factors for residual disease after breast conservative surgery. Methods This retrospective study was based on patients with invasive breast cancer who have received breast conservative surgery and subsequent completion mastectomy. All patients had a clear resection margin in the initial operation. We analyzed the association between the presence of residual disease during completion mastectomy and the following risk factors： T staging, young age, and presence of extensive intraductal component （EIC）, a close margin, lymphovascular permeation （LVP）, positivity of estrogen receptor, progesterone receptor, and c-erbB-2. Results Residual disease was encountered in 21 （45.7%） of 46 patients; EIC was present in 28 patients （60.9%）, of whom 17 had residual disease. Presence of EIC during breast conservation surgery was associated with a higher risk of residual disease during completion mastectomy （P=0.011）. Other variables were not statistically significant risk factors for presence of residual disease. No local recurrence was recorded in our cohort, and the disease-free survival and overall survival after completion mastectomy were similar for patients who had residual disease and those who had not. Conclusions The presence of EIC is a significant risk factor for residual disease in patients after breast conservative surgery. Our findings may suggest the indicated value of completion mastectomy in patients with EIC during initial breast conservative surgery to decrease the risk of subsequent local failure.

Detection of multiple clustered microcalcifications by mammography following breast-conserving surgery

Breast cancer is the most common cause of cancer related death among women around the world. Each year, 1.1 million more women are diagnosed with it, representing more than 10% of all new cancer cases annually. With more than 410 000 deaths each year, the disease accounts for more than 1.6% of all female deaths worldwide. Prompt diagnosis and appropriate treatment may increase life expectancy and recovery rate.

Radical versus conservative surgical treatment of liver hydatid cysts： a meta-analysis

To date, the efficacy of radical surgery （RS） versus conservative surgery （CS） for liver hydatid cysts （LHC） remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.
