RESUMO
Geethu Babu The coronavirus pandemic has created havoc in every aspect of life including cancer care and was declared a pandemic. This audit was conducted to study the impact of the pandemic on diagnosis and treatment of newly diagnosed breast cancer patients at a tertiary cancer center in South India. A total of 1,647 patients who registered at Regional Cancer Centre (RCC), Thiruvananthapuram, Kerala, India for breast cancer during the period April 1, 2020, to September 30, 2020 (COVID-19 period) as well as April 1, 2019, to September 30, 2019 (pre-COVID-19 period) were included in the study. Data regarding the geographic distribution, stage at presentation, time factors for reporting for care, diagnosis, and treatment, referral for care elsewhere were collected and analyzed. The study was approved by the Institutional Review Board. Means and ranges were calculated for continuous type variables, and numbers and percentages for categorical variables. To determine whether there were significant differences between the two groups, independent t -test was used for continuous variables and chi-square test for categorical type of variables. A notable reduction (36%) in newly diagnosed breast cancer patients was seen in 2020 when compared with 2019. There was a significant difference in the geographic distribution of patients in both cohorts ( p = 0.001) and a notable reduction in the number of patients reporting to RCC for treatment from the northern districts of Kerala (81%) and outside Kerala (89.5%). There was no significant difference in the time (in weeks) since symptom onset and reporting to hospital or the clinical stage at diagnosis between the groups. Also, coronavirus disease 2019 (COVID-19) did not seem to negatively impact time intervals between date of registration and pathological diagnosis or start of primary treatment. More patients received neoadjuvant systemic therapy during 2020 compared with 2019, and this difference was statistically significant ( p = 0.004). There was no difference in the type of surgery (breast-conserving surgery vs. modified radical mastectomy). The results demonstrate that COVID-19 did not appear to negatively impact the diagnosis and treatment of newly diagnosed breast cancer patients. However, this is largely attributable to the significantly less number of patients who registered, for whom the departments were able to maintain timely cancer care despite the difficult pandemic times. Significantly more patients received neoadjuvant systemic therapy in 2020.
RESUMO
Liposarcoma (LPS) is a rare malignancy of adipocytic differentiation. According to World Health Organization classification, LPS comprises of four principle subtypes Atypical lipomatous tumor/Well-differentiated liposarcoma (ATL/WDLPS), Dedifferentiated liposarcoma (WDLPS), Myxoid liposarcoma (MLPS), and Pleomorphic liposarcoma (PLPS). Each subtype can develop at any location and shows distinct clinical behavior and treatment sensitivity. ATL/ WDLPS subtype has a higher incidence rate, low recurrence, and is insensitive to radiation and chemotherapy. DDLPS is the focal progression of WDLPS, which is aggressive and highly metastasizing. MLPS is sensitive to radiation and chemotherapy, with a higher recurrence rate and metastasis. PLPS subtype is highly metastasizing, has a poor prognosis, and exhibiting higher recurrence rate. Initial histological analysis provides information for the characterization of LPS subtypes', further molecular and genetic analysis provides certain subtype specifications, such as gene amplifications and gene fusions. Such molecular genetic alterations will be useful as therapeutic targets in various cancers, including the LPS subtypes. A wide range of novel therapeutic agents based on genetic alterations that aim to target LPS subtypes specifically are under investigation. This review summarizes the LPS subtype classification, their molecular genetic characteristics, and the implications of genetic alterations in therapeutics.

Primary sacral tumors are uncommon and sacrectomy is a complex surgical procedure with substantial risk of morbidity. We conducted a retrospective study of patients who had undergone sacral resections for primary sacral tumors between 2010 and 2020. Ten sacral resections including five type 1 sacrectomy (S1 resected), four type 2 (S1 spared), and one type 3 (S3 spared) were performed during the above period. The median age was 47 years and the most common histologic diagnosis was chordoma (50%). The median operating time was 705 min (range 180-960 min) with a median blood loss of 3400 ml (range 500-7000 ml) and a median duration of hospital stay of 13.5 days (range 7-68 days). All patients who underwent type 1 sacrectomy experienced major complications (Clavien-Dindo grade 3 or above) including one death in the immediate perioperative period. Microscopically positive margins (R1) were noted in two patients (20%). All patients with type 1 sacrectomy had R0 resection. The median follow-up period was 31 months. The median MSTS score was 12 (range 4-27). A total of seven patients (70%) had a minimum follow-up of 2 years without disease recurrence. Sacral resection for primary tumors of the sacrum with oncologically safe margins is feasible. Although associated with substantial perioperative morbidity, a detailed preoperative planning and execution of the surgery by a team of orthopedic oncosurgeon, surgical oncologist, and plastic surgeon offer a hope for survival in patients with acceptable functional outcome.
RESUMO
BACKGROUND: Lack of druggable targets and complex expression heterogeneity of known targets is common among TNBC subtypes. An enhanced expression of galectin-3 in TNBCs has already been documented. We have observed a tumor progression-dependent galectin-3 expression in TNBCs compared to adjacent epithelium and non TNBCs. OBJECTIVE: To unravel the association of galectin- 3 in tumor progression, aggressiveness and drug resistance in TNBC patients. METHODS: Galectin-3 expression in 489 breast cancer tissues was correlated with clinicopathological features and the results were validated in cell lines and mouse model by silencing galectin-3 using shRNA and the proteins were profiled by western blot and qRT-PCR. Protein interaction was analyzed by GFP Trap and Mass spectrometry. RESULTS: Galectin-3 expression correlated with tumor stage in TNBC and a lower galectin-3 expression was associated with poor patient survival. The positive correlation between galectin-3, vimentin and CD44 expression, pinpoints galectin-3 contribution to epithelial to mesenchymal transition, drug resistance and stemness. Vimentin was found as an interacting partner of galectin-3. Duplexing of galecin-3 and vimentin in patient samples revealed the presence of tumor cells co-expressing both galectin-3 and vimentin. In vitro studies also showed its role in tumor cell survival and metastatic potential, elementary for tumor progression. In vivo studies further confirmed its metastatic potential. CONCLUSIONS: Tumor progression dependent expression pattern of galectin 3 was found to indicate prognosis. Co-expression of galectin-3 and vimentin in tumor cells promotes tumor dissemination, survival and its metastatic capability in TNBCs.

Sentinel lymph node biopsy (SLNB) is the gold standard for the evaluation of axilla in clinically node-negative early breast cancers. There is limited data on the role and efficacy of the same in the post lumpectomy scenario. This prospective interventional study was conducted over 1 year on 30 post lumpectomy pT1/2 cN0 patients. SLNB was performed by preoperative lymphoscintigram using technetium-labeled human serum albumin followed by intraoperative blue dye injection. Sentinel nodes were identified based on blue dye uptake and gamma probe and sent for intra operative frozen section. Completion axillary nodal dissection was performed in all cases. The primary end point was sentinel node identification rate and accuracy of nodal frozen section. Sentinel node identification rate was 86.7% (n = 26/30) for scintigraphy alone and 96.7% (n = 29/30) using combined method. Average sentinel nodal yield/patient was 3.6 (range 0-7). Maximum yield was seen for hot and blue nodes (1.86). Sensitivity (n = 9/9) and specificity (n = 19/19) of frozen section were 100% with a false negative rate of 0% (0/19). Demographic factors such as age, body mass index, laterality, quadrant, biology, grade, and pathological T stage had no impact on the identification rate. Sentinel lymph node using dual tracer has a high identification rate and a low false negative rate post lumpectomy. Age, body mass index, laterality, quadrant, grade, biology, and pathological T size had no impact on the identification rate.
RESUMO
Context: Tumor budding (TB), poorly differentiated clusters (PDCs), and Ki 67 index are proven adverse prognostic factors in breast carcinoma. Though the relation of Ki 67 index with molecular subtypes of breast carcinoma have been extensively studied, there is very limited information on the role of TB and PDCs. Aims: To grade TB, PDCs, and Ki 67 index and assess histological features and relationship of all these with molecular subtypes of invasive breast carcinoma of no special type. Methods and Material: Retrospective study of 148 cases from 1/1/2019 to 30/12/2019. Division of molecular groups - Luminal A, Luminal B, Her2 neu positive, and triple-negative breast carcinomas (TNBC), and Ki 67 index grades based on St Gallen criteria, intratumoral and peritumoral TB and PDC grades as per the International Tumor Budding Consensus Conference (ITBCC) criteria for colon and correlation between these and other histological features with the molecular subtypes were done. Statistical Analysis: Chi-square test, univariate and multivariate logistic regression models were used. Results: Significant correlation was seen between TB and lymphovascular emboli, Luminal B tumors with high-grade TB and PDCs, Her 2 neu positive and TNBC tumors with low-grade TB, circumscribed tumor margins, tumor necrosis, and Luminal B, Her 2 neu positive and TNBC tumors with larger tumor size and high nuclear grades. Conclusions: TB and PDCs are useful in the prognostication of Luminal A and B tumors when the Ki 67 index values are low/intermediate. Her 2 neu positive and TNBC tumors have a high nuclear grade with necrosis and no association with TB or PDCs.

INTRODUCTION: Surgery in older adults with cancer is complex due to multiple age related confounding factors. There are many scoring systems available for preoperative risk stratifications of older patients. Currently very few prospective studies comparing the various commonly used scales are available. This is the first study which compares the established preoperative risk assessment tools of Eastern Cooperative Oncology Group Performance Scale (ECOG) and American Society of Anaesthesiologists Physical Status Scale (ASA) with frailty scores of Modified Frailty Index (MFI) and Clinical Frailty Scale (CFS). MATERIAL AND METHODS: This is a prospective observational study of older patients with cancer who underwent oncosurgery in a tertiary cancer centre during the one-year study period. Patients were scored on the CFS, MFI, ASA and ECOG scales. All patients were followed up for 30 days immediately following surgery and their post operative complications were documented. Univariate and multivariate analyses were done and a p value of ≤0.05 was considered statistically significant. RESULTS: Of the 820 patients studied, 15.6% had prolonged hospital stay, 9.1% had 30-day morbidity, 0.7% had readmission, and mortality was 1.1%. High-risk scores on the ASA and CFS were significantly associated with prolonged postoperative stay, readmission, morbidity, and mortality (p < 0.05). High-risk scores on the ECOG was significantly associated with prolonged hospital stay (p = 0.027), 30-day morbidity (p = 0.003), and mortality (p = 0.001), but not with readmission. There was no significant association between MFI score and the postoperative variables studied (p > 0.05). On multivariate analysis, morbidity was significantly associated only with male gender (p = 0.015), higher cancer stage (p = 0.005), higher ASA score (p = 0.029), and prolonged hospital stay (p = 0.001). Mortality was significantly associated only with emergency surgery (p = 0.012) and prolonged hospital stay (p = 0.004), and prolonged hospital stay was significantly associated with advanced cancer stage (p = 0.001) and emergency surgery (p = 0.02). CONCLUSIONS: In older patients undergoing cancer surgery, ASA and CFS are predictors of prolonged postoperative stay, morbidity, mortality, and readmission. A high-risk ECOG score is predictive of prolonged post operative stay, 30-day morbidity, and mortality, but not of readmission. Score on MFI is not a predictor of postoperative outcomes. Newer predictive tools which include cancer- specific factors are required for better management of these patients.

Breast cancer is the most common cancer in women globally(1). It is usually a disease of old age. The incidence of breast cancer in females younger than 40 years is as low as 0.5%. Disease in patients with age less than or equal to 40 years at diagnosis is usually considered a young breast cancer(2). Occurrence of more adverse pathological features like triple negative and Her2 positive breast cancer as well as lacking reliable screening methods in young women leads to the poor prognosis in this group of patients(3). In the present study we aim to find the clinical and pathological characteristics of breast cancer in young women and their survival outcome for 5 years comparing the same with those characteristics of the older patients. Patients with nonmetastatic carcinoma breast who had registered at Regional Cancer Centre, Trivandrum, during the year 2012 were selected for the study. Patient's details including the clinicopathological features, treatment details, oncologic outcomes including recurrence, and survival data until 31 July 2019 were collected from treatment files kept in the hospital and via telephonic interview. Kaplan-Meier method was employed for survival analysis. Survival comparison was done using the log-rank test. Cox proportional hazards regression analysis was done for assessing the risk. Out of 1611 curatively treated patients with carcinoma breast, 281 (17.44%) were young breast cancer (equal to or less than 40 years). The median follow-up period was 82 months. Median age of diagnosis was 51.3 years. Young patients presented with larger tumour size, but nodal stage and composite stage, were not different. They had more TNBC status, 35% vs. 24%, p = 0.001. Young patient group had a drop in 5-year OS but statistically insignificant (75.9% vs. 82.5%, p = 0.179) and marginally significant drop in DFS (68.1% vs. 73.8%, p = 0.064). The proportion of young breast cancer is very high in the Indian population. Age is not an independent risk factor for worse prognosis. T and N stage, Her2nue status, and adequacy of nodal clearance are the most important independent risk factors deciding the 5-year OS.
RESUMO
Limberg flap is currently not commonly used in breast oncoplasty. We present our experience with Limberg flap reconstruction in breast cancer patients who underwent breast conservation surgery. This study was conducted at a tertiary cancer centre in Kerala, India. We reviewed the records of patients with breast cancer who underwent Limberg flap reconstruction with breast conservation surgery from 1st January 2020 to 31st October 2021. Data collected included age, quadrant of tumour, side of tumour, T and N stage, status at surgery (primary or post neoadjuvant therapy), type of surgery, flap complications following surgery and breast deformity following surgery. Seventeen patients underwent Limberg flap reconstruction during the study period. The median age of the patients was 51 years. The commonest stage was cT1N0M0. Twelve patients underwent primary surgery and 5 post neoadjuvant chemotherapy. No patient had postoperative flap complications or breast deformity. Limberg flap is simple, versatile and robust and should be a part of the armamentarium of breast surgeons.
RESUMO
Introduction Breast cancer survivors are the largest group of female cancer survivors. Oncologic breast surgery can have a profound impact on a woman's body image and sense of self that can significantly affect their quality of life (QOL). The paucity of data about the effect of type of surgery on QOL of Indian breast cancer survivors has led to this study. Materials and Methods This prospective study included consecutive female early breast cancer patients who underwent primary surgery, that is, breast conservation surgery (BCS) or modified radical mastectomy (MRM) from January 1, 2015 to December 31, 2015. The primary objective was the comparison of QOL using European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and EORTC QLQ-BR 23 between the two groups at 6 months and 1 year postsurgery with the baseline. Results One hundred and thirty-eight patients were included of which 62 underwent BCS and 76 underwent MRM. BCS patients fared better with respect to physical functioning, dyspnea, fatigue, appetite loss, and body image at 6 months ( p < 0.05) as compared with MRM. At 1 year postsurgery, BCS patients fared better with respect to physical functioning, role functioning, global health status, body image, sexual enjoyment, and dyspnea, while MRM patients fared better in emotional functioning and future prospectives ( p < 0.05). Conclusion Patients undergoing BCS have a better QOL with respect to various functional and symptom scales at 6 months and 1 year. However, patients undergoing MRM perform better in terms of future perspective and emotional functioning at 1 year.

OBJECTIVE: The objective of this study is to review the superficial incisional surgical site infections (SISSIs) in emergency surgery in cancer patients. MATERIAL AND METHODS: The microbiological culture and sensitivity reports of patients undergoing emergency surgery for cancer of 1 year (April 2016 to March 2017) were analyzed along with the clinical factors associated with it from a surgeon's perspective. RESULTS: Of the 308 patients who underwent surgery, SISSI rate was 11.7%. The most common organism was Escherichia coli (27%) followed by enterococci (21%). Prolongation of hospital stay was average 2 days. Mortality rate among SISSI patients was 7.9%. Concordance among ongoing antibiotic and culture was 72%. CONCLUSION: Regular review of the current microbial spectrum and its antibiotic spectrum is required, especially in immunocompromized cancer patients.

Pneumocytoma is a rare benign neoplasm which was described over 50 years ago. Over the years its nomenclature and histogenesis has been a subject of much debate and controversy. We would like to report a case of a lady who presented with complaints of cough and hemoptysis. X-ray chest and computerized tomography (CT) scan showed a solitary pulmonary nodule. Biopsy was inconclusive. She underwent a left lower lobectomy. Her postoperative period was uneventful. Her final diagnosis was of pneumocytoma. She is on regular follow-up and is asymptomatic at present.
RESUMO
AIM: Postcricoid cancer is an aggressive neoplasm that presents specific therapeutic problems. This study compares laparoscopic stomach mobilization following total pharyngolaryngoesophagectomy (TPLE) with open mobilization following TPLE with respect to postoperative recovery, perioperative morbidity, and mortality. SUBJECTS AND METHODS: This is a retrospective study in a contemporary series of patients with resectable postcricoid cancer from a single institute (Gujarat Cancer & Research Institute, M.P. Shah Cancer Hospital, Ahmedabad, Gujarat, India). Twenty-five consecutive patients who underwent laparoscopic TPLE were compared with 40 patients who underwent open TPLE from January 2006 to December 2010. RESULTS: Laparoscopic and open TPLE procedures were compared with respect to patient demographics, operative information (blood loss, duration), and complications. The mean duration of surgery was 3.5 hours in the laparoscopic group and 5.5 hours in the open group. The respective mean blood loss was 290 mL and 460 mL. The respective mean time to full oral intake was 10 days and 11 days. The respective average duration of hospitalization was 13 days and 17 days. In the laparoscopic group, 3 (12%) and 4 (16%) patients had pneumonic consolidation and wound infection, respectively, compared with 8 (20%) and 8 (20%) patients in the open group. In the laparoscopic group, there were two (8%) perioperative deaths, compared with four (10%) in the open group. CONCLUSIONS: Laparoscopic TPLE is safe with less morbidity and mortality and quicker postoperative recovery compared with open surgery.
