RESUMEN
Breast cancer (luminal and triple-negative breast cancer [TNBC]) is the most common cancer among women in India and worldwide. Altered sphingolipid levels have emerged as a common phenomenon during cancer progression. However, these alterations are yet to be translated into robust diagnostic and prognostic markers for cancer. Here, we present the quantified sphingolipids of tumor and adjacent-normal tissues from patients of luminal (n = 70) and TNBC (n = 42) subtype from an Indian cohort using targeted liquid chromatography mass spectrometry. We recorded unique sphingolipid profiles that distinguished luminal and TNBC tumors in comparison to adjacent normal tissue by six-sphingolipid signatures. Moreover, systematic comparison of the profiles of luminal and TNBC tumors provided a unique five-sphingolipid signature distinguishing the two subtypes. We further identified key sphingolipids that can stratify grade II and grade III tumors of luminal and TNBC subtype as well as their lymphovascular invasion status. Therefore, we provide the right evidence to develop these candidate sphingolipids as widely acceptable marker/s capable of diagnosing luminal vs TNBC subtype of breast cancer, and predicting the disease severity by identifying the tumor grade.

BACKGROUND: Breast cancer (BC) is the most common malignancy with very high incidence and relatively high mortality in women. The PIK3CA gene plays a pivotal role in the pathogenicity of breast cancer. Despite this, the mutational status of all exons except exons 9 and 20 still remains unknown. METHODS: This study uses the whole exome sequencing (WES) based approach to identify somatic PIK3CA mutations in Indian BC cohorts. The resultant hotspot mutations were validated by droplet digital PCR (ddPCR). Further, molecular dynamics (MD) simulation was applied to elucidate the conformational and functional effects of hotspot position on PIK3CA protein. RESULTS: In our cohort, PIK3CA showed a 44.4% somatic mutation rate and was among the top mutated genes. The mutations of PIK3CA were confined in Exons 5, 9, 11, 18, and 20, whereas the maximum number of mutations lies within exons 9 and 20. A total of 9 variants were found in our study, of which 2 were novel mutations observed on exons 9 (p.H554L) and 11 (p.S629P). However, H1047R was the hotspot mutation at exon 20 (20%). In tumor tissues, there was a considerable difference between copy number of wild-type and H1047R mutant was detected by ddPCR. Significant structural and conformational changes were observed during MD simulation, induced due to point mutation at H1047R/L position. CONCLUSIONS: The current study provides a comprehensive view of novel as well as reported single nucleotide variants (SNVs) in PIK3CA gene associated with Indian breast cancer cases. The mutation status of H1047R/L could serve as a prognostic value in terms of selecting targeted therapy in BC.
RESUMEN
This study analyzed the surgical outcomes after initial implementation of a cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) program in government settings in India. Methods: Ovarian cancer patients undergoing cytoreductive surgery and HIPEC from May 2015 to April 2019 were identified from a prospectively maintained database. Treatment characteristics and surgical outcomes were analyzed. Results: The study identified 101 patients. The mean peritoneal cancer index (PCI) was 7 ± 6, with higher PCI scores in primary and recurrent cases. Major morbidities were recorded in 24.7% of patients. High PCI score, completeness of cytoreduction and major morbidities were independent predictors of overall survival in multivariate analysis. Conclusion: The application of HIPEC in limited-resource settings is feasible with acceptable major morbidities. This program should receive similar priority in government systems.

BACKGROUND: Medical discipline in India focuses on cure rather than comfort care. Palliative care is concerned with improving quality of life and relieving sufferings in patients with advanced incurable terminal diseases. Palliative care in India is still in infancy stage due to lack of knowledge, attitude and skills among health care providers. The reason being lack of training in under graduate as well as postgraduate teaching curriculum and lack of sensitization among policy makers. AIMS AND OBJECTIVES: To assess the awareness, interest, practices and knowledge in palliative care among medical professionals working in a tertiary care hospital. MATERIALS AND METHODS: All participants were mailed proforma to be filled in a fixed format including details of their qualification, demographic data, their field of work, their training in palliative care and multiple choice questions regarding awareness interest, practices and knowledge of palliative care. RESULTS: Out of 186 respondents, 56% had not received any basic training in palliative care. 81% wanted palliative care education to be included in undergraduate curriculum. Poor program was identified as the most common barrier in learning palliative care. 77% respondents had no idea about home based palliative care services. 50.8% patients dies in hospital in their terminal stage. 88% were interested in learning safe opioid practices. Although 89.8% were aware of the need of palliative care in metastatic cancer but less than 50% were aware of the fact that palliative care is also required in MDR-TB and mental illness. CONCLUSION: This study reflects data of an apex cancer institute of the country. The result of awareness is not very encouraging despite a dedicated palliative care department. So, we can assume what will be the palliative care status in other parts of India where there is no palliative care at all. RECOMMENDATION: We strongly recommends that palliative care teaching should be incorporated in undergraduate curriculum to sensitize the students from the beginning. Budding residents in their learning phase can play an important role by learning and providing palliative care as the first person to come into contact with the patients are residents. There is a strong need of spreading palliative care awareness all over the country.

CONTEXT.: Salivary gland (SG) neoplasms (SGNs) display considerable immunophenotypic diversity. A significant proportion of SG carcinomas develop metastases with increased diagnostic difficulty at metastatic sites. Transcriptional repressor GATA binding 1 (TRPS1), a novel immunohistochemical marker for breast cancer, has been found to stain certain SGNs. OBJECTIVE.: To investigate TRPS1 and SRY-related HMG-box 10 (SOX10) immunoexpression in various SGNs and non-SG carcinomas, head and neck paragangliomas, and head and neck mucosal melanomas. DESIGN.: TRPS1 immunoreactivity score (IRS) was determined as negative or low, intermediate, or high positive; SOX10 was reported as negative or positive. RESULTS.: One hundred forty-eight SGNs, 5 breast carcinomas, 105 nonbreast-non-SG carcinomas, including 33 head and neck squamous cell carcinomas (HNSCCs), 6 head and neck paragangliomas, and 6 head and neck mucosal melanomas, were assessed for TRPS1. All 23 benign SGNs showed TRPS1 positivity, with the majority having high-positive IRS (17 of 23 cases; 74%). Among 125 SG carcinomas, 115 of 125 (92%) were TRPS1 positive, with high-positive IRS in 94 of 125 (75%), intermediate positive in 15 of 125 (12%), and low positive in 6 of 125 (5%). Among nonbreast-non-SG carcinomas, HNSCC, lung, thyroid, kidney, and ovarian carcinomas showed frequent TRPS1 staining. Nearly half of HNSCCs had high (11 of 18; 33%) or intermediate (4 of 18; 12%) positive IRS. Mean IRS in SG carcinomas was significantly higher than that in nonbreast-non-SG carcinomas (P < .001). None of the TRPS1-positive nonbreast-non-SG carcinomas expressed SOX10. CONCLUSIONS.: TRPS1 is positive in most benign and malignant SGNs. Its expression in several nonbreast-non-SG carcinomas indicates that it lacks specificity for breast and SG carcinomas, even if considering only high-positive IRS. Addition of SOX10 can increase discriminatory utility of TRPS1.
RESUMEN
The sinonasal tract is considered a second hotspot for human papillomavirus (HPV)-related tumors in the head and neck, with HPV being identified in up to 62% of squamous cell carcinomas (SCCs) and 38% of papillomas. There is limited data from geographical regions with low prevalence of high-risk (HR)-HPV on the association of HR-HPV in sinonasal neoplasms and on utility of p16 as a surrogate marker. p16 immunohistochemistry, HR-HPV mRNA ISH and quantitative real-time PCR (qPCR) were performed on a retrospective cohort of sinonasal papillomas and SCCs. KRAS mutation analysis was done in oncocytic papillomas. p16 positivity was present in 22/142 cases (15.5%) including eight inverted papillomas, one oncocytic papilloma (OP), and 13 SCC. Among these, mRNA ISH showed HR-HPV in the OP and two SCC, while another SCC was found to harbour HPV18 by qPCR. Two HPV-associated SCCs had foci of OP. mRNA ISH was negative in all p16 negative cases. p16 immunohistochemistry showed 68% concordance with mRNA ISH, and had sensitivity and negative predictive value of 100%; specificity was 67%, and positive predictive value was 14.3%. Association with HR-HPV in sinonasal papillomas and SCC is rare, and may be seen in cases demonstrating oncocytic morphology. p16 immunohistochemistry has low specificity and positive predictive value in low-prevalence populations; thus, reflex direct HR-HPV testing should be performed in p16 immunopositive cases. This two-step approach is viable in resource-limited settings, as the proportion of p16 positive cases is small.

Management of advanced ovarian cancer underwent a paradigm shift with advent of cytoreductive surgery and intraperitoneal chemotherapy. Hyperthermic intraperitoneal chemotherapy requires complex machinery and costly disposables, and increased operative time. Early postoperative intraperitoneal chemotherapy is a relatively less resource-intensive alternative way of intraperitoneal drug delivery. We started our HIPEC programme in 2013. In select cases, we offer EPIC. This study is an audit of outcomes to look into the feasibility of EPIC as alternative to HIPEC. We performed analysis of prospectively maintained database in the Department of Surgical oncology from January 2019 to June 2022. We had 15 patients who underwent CRS + EPIC and 84 CRS+ HIPEC. We did a propensity-matched analysis for demographics, baseline data and PCI and compared 15 CRS + EPIC with 15 CRS + HIPEC patients. We compared the perioperative outcomes-morbidity, mortality, length of ICU and hospital stay. Procedure time was significantly higher in the HIPEC compared to EPIC as HIPEC is an intraoperative procedure. Patients were admitted to intensive care unit (ICU) after surgery for a longer mean duration in HIPEC arm (1.4 + 0.7 days) compared to EPIC arm (1.2 + 0.41 days). Patients in HIPEC arm had a significantly shorter hospital stay (mean 7.93 vs. 9.93 days. Four patients in EPIC arm had Clavien-Dindo grade 3 and 4 morbidity compared to 1 patient in HIPEC arm. Hematological toxicity was more common in EPIC group. CRS with EPIC can be explored as an alternative to HIPEC in centres lacking facilities and expertise for HIPEC.
RESUMEN
BACKGROUND: Neoadjuvant chemotherapy (NACT) with human epidermal growth factor receptor 2 (HER2) blockade is the preferred approach for treating early and locally advanced HER2-positive breast cancer. There is a lack of robust data comparing pathological complete response (pCR) and survival outcomes in anthracycline-free and anthracycline-containing regimens with single HER2-targeted therapy. OBJECTIVES: The present study retrospectively evaluated pCR between two groups: Single HER2-targeted therapy with and without anthracycline. METHODS: A total of 215 HER2-positive female breast cancer patients were analyzed who received eitheranthracycline-containing EC-TH (epirubicin and cyclophosphamide, followed by docetaxel and trastuzumab)oranthracycline-free TCH [docetaxel, carboplatin and trastuzumab]. Univariate and multivariate analyses identified prognostic factors for survival and pCR.Kaplan Meier survival curvesdetermined disease-free survival(DFS) and overall survival (OS). RESULTS: Baseline characteristics were comparable in both treatment groups. The pCR rate was 30.8% in the anthracycline-containing EC-TH group and 40.9% in the anthracycline-free TCH group; p = 0.140. Disease-free survival at 3 years (65.8% vs. 58.4%) and 5 years (49.2% vs. 55.2%) was similar between EC-TH and TCH groups, respectively (log-rank p = 0.550). Three-year (95.5% vs. 92.5%) and five-year (84.4% vs. 80.8%) OSwere also comparable between both groups (log-rank p = 0.485). The anthracycline-containing EC-TH group had a higher incidence of febrile neutropenia (6.4%. vs. 3.6%) and cardiac adverse events (7.7% vs. 4.4%) than the anthracycline-free TCH group. CONCLUSION: Neoadjuvant anthracycline-free chemotherapy has similar pCR and survival outcomeswith favourable cardiac and non-cardiac adverse effect profiles compared with anthracycline-containing chemotherapy.

BACKGROUND: Dose-dense adjuvant chemotherapy has been shown to be associated with improved long-term survival outcomes in triple-negative breast cancer (TNBC). However, there is a lacuna of data on the benefits of dose-dense neoadjuvant chemotherapy (NACT) in TNBC. METHODS: This retrospective study included 217 newly diagnosed cases of TNBC treated with a sequential anthracycline and taxane-based NACT, followed by definitive surgery. Study groups consisted of 137 patients who received 3-weekly conventional chemotherapy (cNACT group) and 80 patients with 2-weekly dose-dense NACT (ddNACT group). Pathological complete response (pCR) rates, relapse-free survival (RFS), overall survival (OS), and grade-3/4 chemotoxicities were compared across the groups. RESULTS: No significant difference in the pCR rate (32.8% versus 31.3%; P = 0.808) was observed across the study groups. Relapse rate was lower in the ddNACT group compared to the cNACT group (odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.27-0.95). However, ddNACT had no RFS advantage over conventional chemotherapy (median RFS: not reached versus 56.1 months in cNACT; hazard ratio: 0.90, 95% CI: 0.52-1.53). OS was also comparable in both the groups with a 3-year survival rate of 78.8% (95% CI: 60.9-89.2) in the ddNACT group versus 84.3% (95% CI: 74.8-90.4) in the cNACT group. Younger age, menopause, the Eastern Cooperative Oncology Group ECOG status, and pCR were significantly associated with OS in our cohort. Grade-3 toxicities were comparable in both groups. CONCLUSIONS: This observational study focusing on ddNACT among TNBC patients demonstrated significant differences in the relapse rate with no survival benefits. Differential effects of ddNACT by tumor presentation (early vs. late), tumor size, tumor biology, and cost-benefits of granulocyte colony-stimulating factor support with such regimens need further exploration.

BACKGROUND: Breast cancer is a multifactorial disease which involves number of molecular factors that are critically involved in proliferation of breast cancer cells. MEN1 gene that is traditionally known for its germline mutations in neuroendocrine tumors is associated with high risk of developing breast cancer in females with MEN1 syndrome. However, the paradoxical role of MEN1 is reported in sporadic breast cancer cases. The previous studies indicate the functional significance of MEN1 in regulating breast cells proliferation but its relevance in development and progression of breast cancer is still not known. Our study targets to find the role of MEN1 gene aberration and its clinical significance in breast cancer. METHODS: Breast tumor and adjacent normal tissue of 142 sporadic breast cancer patients were collected at the time of surgery. The expression analysis of MEN1 mRNA and protein was done through RT-PCR, immunohistochemistry and western blotting. Further to find the genetic and epigenetic alterations, automated sequencing and MS-PCR was performed respectively. Correlation between our findings and clinical parameters was determined using appropriate statistical tests. RESULTS: MEN1 expression was found to be significantly increased in the breast tumor tissue with its predominant nuclear localization. The elevated expression of MEN1 mRNA (63.38% cases) and protein (60.56% cases) exhibited a significant association with ER status of the patients. Most of the cases had unmethylated (53.52%) MEN1 promoter region, which can be a key factor responsible for dysregulated expression of MEN1 in breast cancer cases. Our findings also revealed the significant association of MEN1 mRNA overexpression with Age and lymph node status of the patients. CONCLUSION: Our results indicate upregulated expression of MEN1 in sporadic breast cancer patients and it could be critically associated with development and advancement of the disease.

INTRODUCTION: The BORIS, 11 zinc-finger transcription factors, is a member of the cancer-testis antigen (CTA) family. It is mapped to chromosome number 20q13.2 and this region is genetically linked to the early onset of breast cancer. The current study analyzed the correlation between BORIS mutations and the expression of the protein in breast cancer cases. MATERIALS AND METHODS: A population-based study including a total of 155 breast cancer tissue samples and an equal number of normal adjacent tissues from Indian female breast cancer patients was carried out. Mutations of the BORIS gene were detected by polymerase chain reaction-single standard confirmation polymorphisms (PCR-SSCP) and automated DNA sequencing and by immunohistochemistry for BORIS protein expression were performed. The observed findings were correlated with several clinicopathological parameters to find out the clinical relevance of associations. RESULTS: Of all the cases 16.12% (25/155) showed mutations in the BORIS gene. The observed mutations present on codon 329 are missense, leading to Val> Ile (G>A) change on exon 5 of the BORIS gene. A significant association was observed between mutations of the BORIS gene and some clinicopathological features like nodal status (p = 0.013), estrogen receptor (ER) expression (p = 0.008), progesterone receptor (PR) expression (p = 0.039), clinical stage (p = 0.010) and menopausal status (p = 0.023). The protein expression analysis showed 20.64% (32/155) samples showing low or no expression (+), 34.19% (53/155) with moderate expression (++), and 45.17% (70/155) showing high expression (+++) of BORIS protein. A significant association was observed between the expression of BORIS protein and clinicopathological features like clinical stage (p = 0.013), nodal status (p = 0.049), ER expression (p = 0.039), and PR expression (p = 0.027). When mutation and protein expression were correlated in combination with clinicopathological parameters a significant association was observed in the category of high (+++) level of BORIS protein expression (p = 0.017). CONCLUSION: The BORIS mutations and high protein expression occur frequently in carcinoma of the breast suggesting their association with the onset and progression of breast carcinoma. Further, the BORIS has the potential to be used as a biomarker.

INTRODUCTION: Re-operative thyroid surgery (RTS) is performed in patients of differentiated thyroid cancer (DTC) with residual or recurrent disease. However, there is a paucity of literature discussing experience and technique of RTS. This study aims to address this gap by providing a comprehensive review of RTS for DTC, utilizing experiences from a dedicated complex thyroid surgical oncology program at the apex hospital in a developing country. METHODS: A retrospective analysis was conducted using data from the Department of Surgical Oncology's thyroid cancer database. The study period spanned from 2006 to 2022. Clinical presentation, prior surgical history, operative details of RTS, and post-operative outcomes were assessed. Descriptive analysis was performed. RESULTS: During the study period, a total of 182 patients underwent re-operative thyroid surgery (RTS). The primary surgeries performed prior to RTS included near-total or total thyroidectomy in most cases (69.2%), and approximately half of the patients (48.4%) had prior neck node interventions. The RTS procedures consisted of completion total thyroidectomy in 30.8% of cases and surgery for thyroid bed recurrence in 9.9% of cases, while central node dissection was performed in 46.2% of patients and unilateral or bilateral template neck dissection was performed in 41.8% of cases. Extended resections were required in 9.3% of patients. Post-operative complications included permanent hypoparathyroidism (2.7%) and unilateral recurrent laryngeal nerve palsy (1.6%). CONCLUSIONS: RTS is a complex procedure with high rates of post-operative morbidity reported in literature. Optimal outcomes require a multidisciplinary approach, thorough assessment, and skilled surgeons.

OBJECTIVE: To evaluate the role of shear wave elastography (SWE) of suspicious axillary lymph nodes and its combination with B-mode USG in predicting nodal metastasis in breast cancer patients. METHODS: Prospective observational study was performed from June 2018 to August 2020 on breast cancer patients with suspicious axillary nodes on USG. B-mode features (cortical thickness, effacement of fatty hilum, non-hilar blood flow and round shape) and SWE parameters (Emax, Emin, Emean and ESD) of the node with the thickest cortex were evaluated. Diagnostic performances of USG, SWE and their combination were estimated using pathological status of the node on biopsy as the gold standard. RESULTS: Of the 54 patients evaluated, optimal elasticity maps were obtained in 49 nodes of 49 patients (mean age, 46.3 ± 12.1 years; 48/49 (98%) females). On biopsy, 38 nodes (77.6%) had metastasis, while 11 (22.4%) had reactive hyperplasia. Emax, Emin, Emean and ESD of both cortex and hilum were significantly higher in metastatic than reactive nodes. Emax (cortex) ≥14.9 kPa had the best diagnostic performance (sensitivity, 73.7%; specificity, 81.8%). Cortical thickness ≥6.7 mm had the best diagnostic performance among B-mode features (sensitivity, 89.5%; specificity, 72.7%). Combining cortical thickness with effacement of fatty hilum and/or non-hilar blood flow yielded sensitivity of 89.5% and specificity of 90.9%. Addition of Emax (cortex) to cortical thickness and combination of ≥2 B-mode features increased their specificities to 90.9 and 100%, respectively. CONCLUSIONS: Metastatic axillary nodes are stiffer than reactive nodes on SWE in breast cancer patients. Emax (cortex) has the best diagnostic performance in differentiating between reactive hyperplasia and nodal metastasis. Combination of Emax (cortex) and cortical thickness increases the specificity for diagnosing metastasis, especially in nodes showing only cortical thickening. ADVANCES IN KNOWLEDGE: Combination of SWE and B-mode USG is highly specific for differentiating metastasis from reactive hyperplasia in suspicious nodes of breast carcinoma patients, especially in nodes with only cortical thickening.

BACKGROUND: Dual targeted therapy with chemotherapy is one of the therapeutic approaches as neoadjuvant treatment in HER2/neu positive breast cancer (BC). However, the safety and efficacy data of dual-targeted, chemotherapy regimen (docetaxel, carboplatin, trastuzumab, & pertuzumab [TCH-P] is limited from the Indian subcontinent. METHODS: This retrospective study aims to evaluate the efficacy and toxicity of neoadjuvant TCH-P regimen in early, locally advanced, and oligometastatic (OM) HER2-positive BC, at All India Institute of Medical Sciences, New Delhi, India, in between the period 2015-2020. Total 6 cycles of 3-weekly neoadjuvant chemotherapy (NACT) protocol containing docetaxel (75 mg/m2), carboplatin (AUC = 6), trastuzumab (8 mg/kg loading followed by 6 mg/kg) and pertuzumab (840 mg loading followed by 420 mg) were planned. Subcutaneous peg-filgrastim was prophylactically administered on day 2 of each cycle. The primary outcome was the pathological complete response (pCR), and secondary outcomes were clinical overall response rate (ORR), rate of breast conservation surgery (BCS) for patients for whom modified radical mastectomy (MRM) was planned and toxicity. RESULTS: Forty-five patients with a median age of 48 years (31-65) were included in this study. The TNM (AJCC-7th edition) stage distribution was stage II, 14 (31.1%); stage III, 29 (64.5%); and stage IV (OM), 2 (4.4%). Clinical node positivity disease was found in 26 (57.8%) cases. Nineteen (42.2%) patients had hormone-positive and 26 (57.8%) cases were premenopausal. The clinical ORR and CR were seen in 100% and 60% respectively. Overall pCR rate was observed in 25 (55.6%) patients (70% in stage II). BCS was performed in 23 (51.1%) cases. In 12 (26.6%) cases, planned MRM was changed to BCS following NACT. Grade 3 and 4 toxicities were diarrhea 7 cases, thrombocytopenia in 6, neutropenia in 4, febrile neutropenia in 1, and anaemia in 2 cases. Ten patients required dose modification. No patient had congestive heart failure or induction death. CONCLUSIONS: This is the first study of the non-anthracycline-based neoadjuvant protocol in HER2 positive BC from India. The TCH-P is an effective, safe, and well tolerated protocol with a pCR rate of 55.6% and 26.6% BCS conversion rate from planned MRM.

BACKGROUNDS/AIMS: Morbidity following Whipple's surgery largely depends upon the pancreatic stump anastomosis leak. Pancreaticogastrostomy is one of the techniques of pancreatic stump reconstruction and is described variously in the literature. Duct to mucosa pancreaticogastrostomy is described either by a large 3-4 cm posterior gastrotomy or by small gastrotomy of 2-3 mm with the use of internal stents along with. We describe clinical outcomes and technique of 2 layer end to side pancreatico-gastrostomy by a small posterior gastrotomy without the use of internal stents. METHODS: Hospital records of 35 patients where the technique of, small posterior gastrotomy end to side duct to mucosa pancreatico-gastrostomy without internal stents, was used for pancreatic stump reconstruction were studied retrospectively. The data were analyzed for demographic details, stage of the disease, and short term outcomes related to surgical procedure. RESULTS: The mean duration of surgery was 7.4 hours. Grade A, B, and C POPF were observed in 10 (28.5%), 3 (8.5%), and 1 (2.8%) of patients respectively. The mean time to remove pancreatic drain was 9 days, and the mean time to start oral feeds was 8.9 days. The mean hospital stay was 12.9 days (07-26). Thirty days mortality was 2.8%. CONCLUSIONS: Unstented duct to mucosa end to side pancreatico-gastrostomy technique is comparable with other pancreatico-gastrostomy techniques in outcomes in terms of POPF, morbidity, mortality, and hospital stay. However, to establish the superiority or inferiority of this technique, a larger study is recommended.
RESUMEN
OBJECTIVE: To evaluate the role of axillary ultrasonography (axUS) and ultrasound-guided pre-operative wire localisation of pre-treatment positive clipped node (CN) for prediction of nodal response to neoadjuvant chemotherapy (NACT) in node positive breast carcinoma patients. METHODS AND MATERIALS: A prospective study was conducted between June 2018 and August 2020 after Ethics Committee approval. Breast carcinoma patients (cT1-cT4b) with palpable axillary nodes (cN1-cN3) and suitable for NACT were recruited after written informed consent. Single, most suspicious node was biopsied and clipped. Nodal response to NACT was assessed on axUS. Wire localisation of CN was performed prior to axillary lymph node dissection (ALND). Diagnostic performances of axUS and CN excision were assessed. RESULTS: Of the 69 patients evaluated, 32 patients (mean age, 43.5 ± 11.8 years; females, 31/32 [97%]; pre-menopausal, 18/32 [56.3%]) with metastatic nodes who received NACT were included. Nodal pathological complete response rate was 34.4% (11/32) overall and 70% (7/10) in patients with ≤2 suspicious nodes on pre-NACT axUS. False-negative rates (FNRs) of axUS and CN excision were 4.8% and 28.6% respectively. Combination of post-NACT axUS and CN excision had an FNR of 4.8% overall and 0% in patients with ≤2 suspicious nodes on pre-NACT axUS. CONCLUSION: Combination of AxUS and ultrasound-guided wire localisation of pre-treatment positive CN has high diagnostic accuracy for nodal restaging after NACT in node positive breast cancer patients. ADVANCES IN KNOWLEDGE: Addition of axUS assessment to wire localisation of CN reduces its FNR for detecting residual metastasis after NACT.

Background Prognosis of metastatic colorectal cancer (mCRC) is poor and goal of treatment is mainly palliative unless there is limited metastatic disease which is surgically resectable. Here, we report a case series of long-term survivors treated predominantly with chemotherapy. Methods This is a single-center retrospective analysis of patients of mCRC. Records of metastatic colorectal cancer patients registered at Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi, between the year 2005 and 2015 were retrieved and reviewed. Inclusion criteria were patients who survived 5 years or more, treated mainly by chemotherapy, with either initial presentation as metastatic disease or those who progressed after initial surgery with or without adjuvant therapy. The details about the patient characteristics, treatment, and outcome were collected. The data were censored on September 30, 2020. Results Records of 370 mCRC patients were reviewed. Thirty-one patients with all the available details fulfilled the criteria for inclusion in the study. Median age was 53 years (range, 22-74 years). Sixteen were women (51.6%). Twenty-four (77%) were newly diagnosed cases with initial presentation as metastatic disease. Commonest site of primary was on the left (21, 67.6%) followed by right side and transverse colon in 5 patients each. Liver was the most common site of metastasis ( n = 18, 58.06%). In metastatic setting, the most common chemotherapy regimen used in the first line was CAPOX ( n = 11, 35.48%). Only three patients could undergo metastatectomy. Monoclonal antibodies could be used only in 14 patients. Median overall survival (OS) of this cohort is 81.6 months (95% confidence interval [CI], 69.73-117.9). Conclusion A small but significant proportion of mCRC patients may achieve and maintain durable responses and long term survival with use of combination of chemotherapy with or without biologics.
RESUMEN
BACKGROUND: The neoadjuvant chemotherapy in HER2-positive breast cancer consists of a chemotherapy backbone and HER2-directed therapy. The increase in cardiotoxicity by the use of trastuzumab with an anthracycline-based regimen has led to the use of nonanthracycline-based alternative regimens. The docetaxel, carboplatin, and trastuzumab (TCH) are one such regimen. The efficacy and toxicity of this regimen have not been widely studied in Indian patients. AIMS: This retrospective study aims to evaluate the efficacy and toxicity of neoadjuvant TCH regimen in locally advanced and oligometastatic HER2-positive breast cancer in Indian patients. METHODOLOGY: The hospital records between January 2014 and December 2016 were reviewed to identify patients with locally advanced and oligometastatic HER2-positive breast cancer treated with uniform 3-weekly neoadjuvant chemotherapy protocol-containing docetaxel (75 mg/m2), carboplatin (AUC = 6), and trastuzumab (8 mg/kg loading followed by 6 mg/kg) (TCH). The primary outcome was the pathologic complete response (pCR), which was defined as an absence of invasive and noninvasive cancer in breast or lymphnode. RESULTS: Thirty-two patients with mean age 46 years met our inclusion criteria, of these 24 patients had locally advanced breast cancer, and eight patients had oligometastatic breast cancer. 13 (40.6%) patients had hormone-positive breast cancer. The objective response rate as assessed clinically was 100%, and pCR rate was 36.3%. The patients with oligometastatic breast cancer also showed a good response to chemotherapy with three patients showing pCR and four patients showing resolution disease at metastatic sites. The patients experienced very few Grade III/IV toxicities, and no patient had clinical congestive heart failure. CONCLUSION: The TCH protocol is an efficacious neoadjuvant chemotherapy regimen for locally advanced and oligometastatic breast cancer and is safe and well tolerated in this population.
