Only 22% were aware of treatment options, while 12% had an idea about BCS. In 90% cases, surgeon was the source of knowledge and despite acquiring the knowledge only 23.7% opted for BCS. The decision regarding the treatment was not taken by the patient in majority of the cases. Our study brings out that there is little to no knowledge about Breast conservation.

This prospective study aimed to evaluate the effectiveness of a novel multilayer closure technique utilizing vascularized muscle flaps designed to obliterate residual pharyngeal dead space and reinforce neopharyngeal healing, with the goal of preventing PCF formation. A prospective single-arm cohort study was conducted on 25 consecutive patients with stage III or IV laryngeal cancer, or recurrent disease following chemoradiation, who underwent total laryngectomy with concurrent neck dissection between 2017 and 2025. The modified technique involved vertical multilayer suturing of the posterior pharyngeal wall combined with tailored vascularized muscle flaps (local, distant, or free) to fill dead space and support the neopharynx. Postoperative care included nutritional optimization, targeted antibiotic prophylaxis, and close monitoring for complications. The primary outcome was the incidence of PCF, compared to the institutional historical baseline rate of 18%. Of the 25 patients (mean age 58 years; 96% male), 60% had prior chemoradiation and 48% were underweight preoperatively. Local muscle flaps, predominantly sternocleidomastoid, were used in 68% of cases; pedicled flaps were used in 88%. Transient hypoalbuminemia occurred in 12% of patients and was corrected with intravenous albumin supplementation. Over a 3-year follow-up, no patient developed PCF or major wound complications. Statistical analysis confirmed a significantly lower PCF rate compared to the institutional baseline (0% vs. 18%, <i>p</i> = 0.007; 95% CI: 0-11.3%). This modified multilayer closure technique with vascularized muscle flap reinforcement demonstrated complete prevention of PCF in a high-risk cohort undergoing salvage laryngectomy.

This article proposes a standardised national curriculum for Surgical Oncology training to ensure consistent training, academic excellence, and improved patient outcomes. The framework integrates surgical expertise, oncologic principles, research aptitude, and holistic care, aligned with global standards yet adapted to India's healthcare realities. Consensus was achieved through online and in-person deliberations among senior surgical oncology leaders from institutes such as AIIMS and other major centres. Several participants have served as subject experts for the National Board of Examinations, the National Medical Commission, and the Indian Council of Medical Research. The framework, informed by global and Indian models, was mapped across cognitive, psychomotor, and affective domains. It incorporated disease-specific competencies, research training, multidisciplinary exposure, and subspecialty rotations. Evaluation strategies included both formative and summative assessments, with inter-institutional exchange where facilities were limited. The three-year curriculum includes academic activities, thesis and database project, logbook maintenance, and rotations in medical oncology, radiation oncology, palliative care, ICU, and basic sciences. Training spans core surgical principles and advanced procedures across organ systems, with emphasis on community health, translational research, digital health, and artificial intelligence. Competency-based progression, structured assessments, and holistic training in ethics, communication, and survivorship are integral features. The proposed curriculum provides a structured, competency-based model for surgical oncology training in India. It strengthens clinical, academic, and research capacities, outlines a roadmap for future organ-based subspecialisation, and offers a framework adaptable to low- and middle-income countries.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13193-025-02433-2.</p>","PeriodicalId":46707,"journal":{"name":"Indian Journal of Surgical Oncology","volume":"17 6","pages":"1323-1338"},"PeriodicalIF":0.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13315055/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148362902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
