RESUMEN

Introduction: The essential goal of neoadjuvant chemotherapy (NACT) is to downstage the primary tumor making it amenable for breast conservation surgery (BCS). However, since the safety of this surgery is paramount, post-NACT breast conservation rates remain low. As per the recommendation of the 2018 Early Breast Cancer Trialists' Collaborative Group (EBCTCG) overview of long-term post-NACT follow-up, we have devised a protocol for imaging, localization, rad-path analysis, and documentation of radiotherapy techniques to ensure the safety of post-NACT breast conservation. Methods: This is a retrospective cohort of 180 breast cancer patients who received NACT and were operated on by a single surgical oncologist from 2015 to 2020. After selection based on published guidelines, patients were treated with neoadjuvant systemic (chemo or hormone) therapy. In cases where primary tumors responded and reduced to 1-2 cm in size mid-NACT, the residual tumors were localized by clips under ultrasound guidance and calcification was wire localized. All patients were treated using appropriate surgical and oncoplastic techniques where indicated. Negative margins were ensured by intra-operative rad-path analysis. Adjuvant chemotherapy and radiotherapy were given as per protocol. Results: In 81 cases that required mastectomy at presentation, we were able to achieve a 72.8% post-NACT BCS rate with the help of oncoplasty. Overall, 142 of 180 (80%) patients were treated with breast conserving surgery of which 80% (121 of 142) were oncoplasty. Margins were assessed on intra-operative frozen and re-excised in the same setting. No positive margins were reported in final histopath of 142 breast conservation procedures. Post-operative complication rates after breast conservation in the first year were at 17% (24 of 142 including two major complications). Patient reported outcomes were satisfactory with increased satisfaction for breast conservation compared with immediate breast reconstruction. Discussion: Employing oncoplastic breast surgery (OBS) techniques following stringent protocols for accurate localization of the residual tumor, intra-operative rad-path analysis, and adjuvant treatments, we show successful breast conservation in 72.8% of our mastectomy-qualified patients after downstaging by NACT. We also report satisfactory outcomes for post-NACT surgery, patient-reported satisfaction, and survival.

RESUMEN

Introduction: The majority of breast cancer patients from India usually present with advanced disease, limiting the scope of breast conservation surgery. Therapeutic mammoplasty (TM), an oncoplastic technique that permits larger excisions, is quite promising in such a scenario and well suited to breast cancer in medium-to-large-sized breasts with ptosis and in some cases of large or multifocal/multicentric tumors. Here, we describe our TM cohort of 205 (194 malignant and 11 benign) patients from 2012 to 2019 treated at a single surgeon center in India, the largest Asian dataset for TM. Methods: All patients underwent treatment after careful discussions by a multidisciplinary tumor board and patient counseling. We report the clinicopathological profiles and surgical, oncological, cosmetic, and patient-related outcomes with different TM procedures. Results: The median age of breast cancer patients was 49 years; that of benign disease patients was 41 years. The breast cancer cohort underwent simple (n = 84), complex (n = 71), or extreme (n = 44) TM surgeries. All resection margins were analyzed through intra-operative frozen-section assessment with stringent rad-path analysis protocols. The margin positivity rate was found to be 1.4%. A majority of the cohort was observed to have pT1-pT2 tumors, and the median resection volume was 180 cc. Low post-operative complication rates and good-to-excellent cosmetic scores were observed. The median follow-up was 39 months. We observed 2.07% local and 5.7% distal recurrences, and disease-specific mortality was 3.1%. At median follow-up, the overall survival was observed to be 95.9%, and disease-free survival was found to be 92.2%. The patient-reported outcome measures (PROMs) showed good-to-excellent scores for all types of TMs across BREAST-Q domains. Conclusion: We conclude that in India, a country where women present with large and locally advanced tumors, TM safely expands the indications for breast conservation surgery. Our results show oncological and cosmetic outcomes at acceptable levels. Most importantly, PROM scores suggest improved overall wellbeing and better satisfaction with the quality of life. For patients with macromastia, this technique not only focuses on cancer but also improves self-image and reduces associated physical discomfort often overlooked by women in the Indian setting. The popularization of this procedure will enable Indian patients with breast cancer to receive the benefits of breast conservation.

RESUMEN

On January 13th and 14th 2022, the Center for Translational Cancer Research organized the virtual third Indian Cancer Genome Atlas (ICGA) Conference 2022 "Biobanking to Omics - Collecting the Global Experience." This conference was planned as the steppingstone to help ICGA understand the road ahead and the probable roadblocks in its preparatory phase as ICGA begins to streamline the tumor tissue biobanking and multi-omics efforts in the Indian subcontinent. The first day of the conference was dedicated to updates on the current status of ICGA, the future prospect, and the global understanding of multi-omics efforts. The key highlights included two keynote speeches by Dr Wui Jin Koh, Senior Vice President and Chief Medical Office, National Comprehensive Cancer Network, and by Dr Christina Curtis, Associate Professor, Stanford University School of Medicine. The first day ended with an intriguing panel discussion on "ICGA updates and Future Steps." The second day focused on biobanking practices across the globe and several aspects of biobank setup such as infrastructure, maintenance, quality control, patient consent, and lessons learned from established biobanking setups. The talk by Rosita Kammler, Head, Translational Research Coordination, International Breast Cancer Study Group, Switzerland, and Ruhul Amin, Director, Bangladesh Medical Research Council were the key highlights. The second day also ended with an engaging panel discussion on "Tumor tissue biobanking - national and international perspectives." Overall, the conference was well received and had good attendance from national and international students, researchers, and faculty from academia as well as industry.

RESUMEN

OBJECTIVES: Evaluation of tumor-infiltrating lymphocytes (TILs) distribution in an Indian cohort of breast cancer patients for its prognostic significance. METHODS: A retrospective cohort of breast cancer patients from a single onco-surgeon's breast cancer clinic with a uniform treatment strategy was evaluated for TILs. Tumor sections were H&E stained and scored for the spatial distribution and percent stromal TILs infiltration by a certified pathologist. The scores were analysed for association with treatment response and survival outcomes across molecular subtypes. RESULTS: Total 229 breast cancer tumors were evaluated. Within spatial distribution categories, intra-tumoral TILs were observed to be associated with complete pathological response and lower recurrence frequency for the entire cohort. Subtype-wise analysis of stromal TILs (sTILs) re-enforced significantly higher infiltration in TNBC compared to HER2-positive and ER-positive tumors. A favourable association of higher stromal infiltration was observed with treatment response and disease outcomes, specifically in TNBC. CONCLUSION: Intra-tumoral TILs showed a higher proportion with favourable association with better patient outcomes in an Indian cohort, unlike western cohorts where both stromal and intra-tumoral TILs show similar association with prognosis. With further validation, TILs can be developed as a cost-effective surrogate marker for treatment response, especially in a low-resource setting such as India.

RESUMEN

Breast reconstruction with an autologous lower dermal sling (ALDS) is an established one-stage procedure in patients with moderate to large ptotic breasts. However, this technique is difficult to perform in small and non/minimally ptotic breasts. We describe our experiences from a single institution about a novel Advanced Autologous Lower Dermal Sling (A-ALDS) technique for reconstruction in small breasts. We performed one-stage nipple/skin sparing mastectomies in 61 patients with immediate reconstruction either by Conventional Immediate Breast Reconstruction Surgery or A-ALDS technique. Mean age of study patients was 46.9 years. We observed significantly better cosmetic score and lower immediate complication rate vis-a-vis skin necrosis, implant loss with the A-ALDS technique (i.e., nil versus 3 in Conventional Immediate Breast Reconstruction Surgery (IBRS)). Forty patients completed 12-month follow-up. The PROMs - Patient Reported Outcome Measures (Breast-Q) revealed good to excellent scores for satisfaction with breast, cosmetic outcome, and psychosocial well-being in patients operated with both these techniques. However, sexual well-being was significantly better in the A-ALDS group. The A-ALDS is a novel, cost-effective, and safe technique for immediate one-stage implant-based reconstruction for small breasts. It provides a dermal barrier flap and hence, ensures less complications, excellent cosmetic results, and patient satisfaction.

RESUMEN

The report evaluates the effect of coronavirus disease (COVID-19) pandemic on breast cancer treatment and management at a single-surgeon cancer care unit in one of the hotspots of COVID-19 in India. In response to the pandemic, the adjustments were made in the clinical practice to accommodate social distancing. Patient consultations were done over phone call or in-clinic visit with prior appointment to reduce the risk of exposure to COVID-19. Total number of patients that were treated at the clinic and the essential surgeries performed during the pandemic phases are summarized in the report. The methodology adopted here for care and management of the cancer patients can serve as a guiding principle for cancer care units in the country.

RESUMEN

BACKGROUND: A breast cancer biobank with retrospectively collected patient data and FFPE tissue samples was established in 2018 at Prashanti Cancer Care Mission, Pune, India. It runs a cancer care clinic with support from a single surgeon's breast cancer practice. The clinical data and tissue sample collection is undertaken with appropriate patient consent following ethical approval and guidelines. METHODS: The biobank holds clinical history, diagnostic reports, treatment and follow-up information along with FFPE tumor tissue specimens, adjacent normal and, in few cases, contralateral normal breast tissue. Detailed family history and germline mutational profiles of eligible and consenting patients and their relatives are also deposited in the biobank. RESULTS: Here, we report the first audit of the biobank. A total number of 994 patients with breast disease have deposited consented clinical records in the biobank. The majority of the records (80%, n = 799) are of patients with infiltrating ductal carcinoma (IDC). Of 799 IDC patients, 434 (55%) have deposited tumor tissue in the biobank with consent. In addition, germline mutation profiles of 84 patients and their family members are deposited. Follow-up information is available for 85% of the 434 IDC patients with an average follow-up of 3 years. CONCLUSION: The biobank has aided the initiation of translational research at our center in collaboration with eminent institutes like IISER Pune and SJRI Bangalore to evaluate profiles of breast cancer in an Indian cohort. The biobank will be a valuable resource to the breast cancer research community, especially to understand South Asian profiles of breast cancer.

RESUMEN

Breast cancer incidence is on the rise in India as in rest of the world. While the advances in overall cancer care are at par, the surgical interventions have not been changing at the same pace in India, as in the rest of the developed world. Partly, this is due to the relatively more advanced state of cancer at detection and partly due to lack of awareness resulting in apprehension and slow acceptance of de-escalation of surgical interventions by the treating surgeons, and the beneficiaries, the patients. The article looks at the current scenario, available evidence on the practices and pitfalls with possible solutions for advancing surgical care of breast cancer in India.

RESUMEN

PURPOSE: Breast cancer is the most common cancer in women in India, with higher incidence rates of aggressive subtypes, such as triple-negative breast cancer (TNBC). METHODS: A systematic review was performed to compute pooled prevalence rates of TNBC among patients with breast cancer, and clinical features at presentation were systematically compared with non-TNBC in an Indian cohort of 20,000 patients. RESULTS: Combined prevalence of TNBC among patients with breast cancer was found to be on the higher side (27%; 95% CI, 24% to 31%). We found that the estrogen receptor (ER) expression cutoff used to determine ER positivity had an influence on the pooled prevalence and ranged from 30% (ER/progesterone receptor [PR] cut ff at 1%) to 24% (ER/PR cutoff at 10%). Odds for TNBC to present in the younger age-group were significantly higher (pooled odds ratio [OR], 1.35; 95% CI, 1.08 to 1.69), with a significantly younger mean age of incidence (weighted mean difference, -2.75; 95% CI, -3.59 to -1.92). TNBC showed a significantly higher odds of presenting with high grade (pooled OR, 2.57; 95% CI, 2.12 to 3.12) and lymph node positivity (pooled OR, 1.39; 95% CI, 1.21 to 1.60) than non-TNBC. CONCLUSION: Systematic review and meta-analysis of 34 studies revealed a high degree of heterogeneity in prevalence of TNBC within Indian patients with breast cancer, yet pooled prevalence of TNBC is high in India. High proportions of patients with TNBC present with aggressive features, such as high grade and lymph node positivity, compared with patients without TNBC. We emphasize the need for standardized methods for accurate diagnosis in countries like India.

RESUMEN

Primary angiosarcoma of the breast is a rare (0.04% of all malignant breast tumors) and potentially life-threatening disease. Given its variable and non-specific clinical, radiological and pathological presentation, accurate diagnosis is a challenge. Primary angiosarcoma of the breast predominantly occurs in younger patients and it is often overlooked and misdiagnosed at radiology and pathology. To ensure that this aggressive malignancy is not overlooked, radiologists need to be aware of the fact that such tumors may present with non-specific imaging features. We report a case of a 32-year-old female with primary angiosarcoma of the breast presenting with non-specific imaging features. It was initially interpreted as a capillary cavernous hemangioma at histopathology following an ultrasound-guided biopsy. This eventually turned out to be angiosarcoma after a second histopathology opinion was sought in light of the radiology-pathology discordance.

RESUMEN

INTRODUCTION: Breast conserving surgery (BCS) followed by radiation therapy (RT) has become the preferred alternative to mastectomy for patients with early stage breast cancer (BC). Randomized trials have confirmed equivalent locoregional control and overall survival for BCS and mastectomy. Extreme Oncoplasty (EO) extends the indications of BCS for patients who would otherwise require mastectomy, ensuring better aesthetic outcomes and oncological safety. METHODS: BC patients with multifocal/multicentric (MF/MC) tumors, extensive DCIS, or large tumor >50mm underwent EO at our breast unit. Therapeutic reduction mammaplasty (TRM) with wise pattern preoperative markings and dual pedicle technique involving parenchymal rearrangement was used for oncoplastic reconstructions in majority of the cases followed by RT. Patient reported outcome measures (PROMs) were assessed using the validated Breast-Q questionnaire. RESULTS: Of the 39 patients in the study, 36 had unilateral and 3 had bilateral BC. Mean age was 47.2 years. Median tumor size was 75mm. 17 (43.6%) patients received NACT; none achieved a complete clinical response. 28 (71.8%) patients were administered to adjuvant chemotherapy. 33(84.6%) patients received RT to the breast with a median dose of 50Gy in 28 fractions and a boost dose of 10Gy in 5 fractions to the tumor bed. No major complications or local recurrences were observed. Excellent Breast-Q scores were observed in patients undergoing EO after 12 months of follow-up. CONCLUSION: EO followed by RT results in acceptable local-regional control, low rate of complications, and high patient satisfaction. In selected patients, EO could provide a safe alternative for breast conservation surgery instead of mastectomy.

RESUMEN

Breast Cancer (BC) treatment leads to mutilation and destruction of breast shape with negative effects on body image and self-esteem.One of the main goals of reconstructive and oncoplastic breast surgery is to satisfy patients and improve their quality of life (QoL).Therefore, it is important to assess the patient experience post-surgery by means of patient-reported outcome measures (PROMs) that focus on the patient's perception of the surgery and surgical care, as well as psychosocial well-being and physical functioning. The objective of the current study was to identify predictors of patient satisfaction such as breast appearance including implant type in a selective sample of women who underwent breast reconstruction surgery using implants. Participants in this prospective study were women, (age 26-75 years) that were newly diagnosed with breast carcinoma. All consecutive patients who underwent breast reconstruction between January 2013 and October 2014 were asked to complete the BREAST-Q questionnaire 1 year after surgery. 120 patients underwent unilateral breast reconstruction using implant. While 38 patients underwent reconstruction with opposite breast reduction symmertization, 27 patients underwent therapeutic mammoplasty. The response rate for BREAST-Q questionnaire completion was 98 % with 147 out of 150 study participants completed the questionnaire. From the data collected from 147 patients, the responses could be distributed into 4 distinct groups based on the reconstruction outcomes namely "very much satisfied" (93 %) or "definitely and mostly satisfied" (94 %) or "satisfied" with the outcome (88 %) or "definitely agree on having reconstruction rather than the alternative of having no breast "(91 %).The results showed significant improvement in all four areas that were evaluated after surgery namely satisfaction with the appearance of the breasts, psychosocial, sexual and physical well-being. While the reconstruction surgery had an overall positive impact on quality of life it was observed that in patients that did not undergo breast reconstruction psychological issues related to sexuality were observed. Many newly diagnosed BC patients do not opt for these new surgical procedures due to psychological trauma or lack of information. Based on these observations, we propose that Breast Cancer Management protocols should also include additional counselling support for the newly diagnosed BC patients on the option of breast reconstruction along with conventional medical treatment counselling by the Oncosurgeon.

RESUMEN

BACKGROUND: Neoadjuvant chemotherapy (NACT) is being increasingly used for patients with large-size operable breast cancer. This phase 2 study of sequential NACT with gemcitabine and doxorubicin (Gem + Dox) followed by gemcitabine and cisplatin (Gem + Cis) was conducted in women with large or locally advanced breast cancer. The objectives were to evaluate the pathological complete response (pCR) rate, toxicity, pathological and genetic markers predicting response, the proportion of patients undergoing breast conservation surgery, progression-free survival (PFS) and overall survival (OS) after 5 years, and time to treatment failure (TtTF). In this manuscript, we report the long-term OS, PFS, and TtTF results. METHODS: Female patients aged at least 18 years with large T2 (at least 3 cm) or locally advanced (T3, T4, or N2) breast carcinoma were included. Treatment consisted of 4 cycles of Gem + Dox (gemcitabine 1,200 mg/m(2) on days 1 and 8 plus doxorubicin 60 mg/m(2) on day 1 of each 21-day cycle), followed by 4 cycles of Gem + Cis (gemcitabine 1,000 mg/m(2) on days 1 and 8 plus cisplatin 70 mg/m(2) on day 1 of each 21-day cycle), and then surgery. RESULTS: Sixty-five patients were enrolled. The pCR rate was 20%. The 5-year OS probability was 71% (95% CI 56-82%), and the 4-year PFS and TtTF probabilities were 63% (95% CI 48-74%) and 45% (95% CI 32-57%), respectively. CONCLUSIONS: NACT with Gem + Dox followed by Gem + Cis was efficacious in patients with operable breast cancer.
