Introduction: Chyle leak is a serious complication following oesophagectomy with incidence varies from 1% to 9%. Near infra-red fluorescence imaging of thoracic duct (TD) can provide real-time dynamic imaging during the surgery. In this study, we intend to compare indocyanine green (ICG) dye instillation through inguinal node with subcutaneous first web space instillation for visualisation of TD during robotic-assisted minimally invasive oesophagectomy (RAMIE) procedure.

Unlabelled: The objective of this study is to analyze oncological outcomes of patients with peritoneal metastases (PM) of colorectal origin treated with Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC).

Background: PIPAC has been demonstrated to be a feasible and safe novel treatment for patients with PM of various origins. Only small series reports on survival after PIPAC by disease entity.

Background: Precise prognostication is the key to optimum and effective treatment planning for early-stage hormone receptor (HR) positive, HER2/neu negative breast cancer patients. Differences in the breast cancer incidence and tumor anatomical features at diagnosis, pharmacogenomics data between Western and Indian women along with the vast diversity in the economic status and differences in insurance policies of these regions; suggest recommendations put forward for Western women might not be applicable to Indian/Asian women. Opinions from oncologists through a voting survey on various prognostic factors/tools to be considered for planning adjuvant therapy are consolidated in this report for the benefit of oncologists of the sub-continent, SAARC and Asia's LMIC (low and middle-income countries).

Objectives: The Enhanced recovery after surgery (ERAS) program is designed to achieve faster recovery by maintaining pre-operative organ function and reducing stress response following surgery. A two part ERAS guidelines specific for Cytoreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) was recently published with intent of extending the benefit to patients with peritoneal surface malignancies. This survey was performed to examine clinicians' knowledge, practice and obstacles about ERAS implementation in patients undergoing CRS and HIPEC.

Background: The application of robotic staplers in surgeries has increased in recent years. Robotic platform enhances ability of the surgeon to directly control and manoeuvre staplers to achieve required angulation and sealing within the confines of the thorax and pelvis. Hence, in this study, we intended to learn the effectiveness of the SureForm SmartFire technology stapling system in various oncological procedures.

Article Synopsis
  • Minimally invasive robotic-assisted surgeries for rectal cancer are becoming popular due to their improved surgical outcomes and efficiency.
  • A study of 262 rectal cancer patients examined the learning curve of surgeons using the cumulative summation technique, identifying three phases: initial, plateau, and mastery.
  • Results showed significant reductions in operative time, console time, and docking time as surgeons gained experience, highlighting the benefits of ongoing self-auditing and technique improvement.

Lung cancer (LC) is one of the leading causes of cancer deaths worldwide. In India, the incidence of LC is increasing rapidly, and a majority of the patients are diagnosed at advanced stages of the disease when treatment is less likely to be effective. Recent therapeutic developments have significantly improved survival outcomes in patients with LC.

Amit Rauthan  Nivolumab monotherapy is approved for the treatment of metastatic renal cell carcinoma (mRCC) patients who have progressed on prior therapies based on the pivotal Checkmate-025 trial. There is limited literature on the efficacy and safety profile of usage of nivolumab in the treatment of mRCC in India in a real-world setting.  A retrospective analysis was performed of patients who received nivolumab monotherapy for mRCC after having progressed on prior therapies.

Background The aim of this study was to analyse survival and surrogates for oncological response after PIPAC for appendiceal tumours. Methods This retrospective cohort study included consecutive patients with appendiceal peritoneal metastases (PM) treated in experienced PIPAC centers. Primary outcome measure was overall survival (OS) from the date of diagnosis of PM and from the start of PIPAC.

Introduction: There are standard treatment guidelines for the surgical management of rectal cancer, that are advocated by recognized physician societies. But, owing to disparities in access and affordability of various treatment options, there remains an unmet need for personalizing these international guidelines to Indian settings.

Methods: Clinical Robotic Surgery Association (CRSA) set up the Indian rectal cancer expert group, with a pre-defined selection criterion and comprised of the leading surgical oncologists and gastrointestinal surgeons managing rectal cancer in India.

Purpose: To understand the actual impact of the Covid-19 pandemic and frame the future strategies, we conducted a pan India survey to study the impact on the surgical management of gastrointestinal cancers.

Methods: A national multicentre survey in the form of a questionnaire from 16 tertiary care gastrointestinal oncology centres across India was conducted from January 2019 to June 2021 that was divided into a 15-month pre-Covid era and a similar period of active Covid pandemic era.

Results: There was significant disruption of services; 13 (81%) centres worked as dedicated Covid care centres and 43% reported suspension of essential care for more than 6 months.

Mucormycosis is a rare, but potentially fatal, fungal infection which is caused by mucormyctes. These forms of fungi are typically known to infect immuno-compromised individuals but are rare in immunocompetent individuals. Herein, we report the case of a 52 year-old female who was diagnosed with right breast carcinoma in Manipal Hospital, a tertiary cancer care center.

Objectives: Safe implementation and thorough evaluation of new treatments require prospective data monitoring and standardization of treatments. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a promising alternative for the treatment of patients with peritoneal disease with an increasing number of suggested drug regimens. The aim was to reach expert consensus on current PIPAC treatment protocols and to define the most important research topics.

Breast cancer is a public health challenge globally as well as in India. Improving outcome and cure requires appropriate biomarker testing to assign risk and plan treatment. Because it is documented that significant ethnic and geographical variations in biological and genetic features exist worldwide, such biomarkers need to be validated and approved by authorities in the region where these are intended to be used.

Women in low- and middle-income countries (LMICs) are significantly more likely to develop and die from invasive cervical cancer, while rates of other gynecologic malignancies are comparable to those faced by women in high-income countries. Despite this increased need, there are few specialist physicians in LMICs available to treat women with gynecologic cancers. Training specialists in low-resource settings faces multiple challenges, including ensuring protected time from other clinical demands, access to best practice guidelines, training that is tailored to the specific challenges faced in the trainee's environment, and isolation from other fully trained professionals and securing support services.

Background: Anastomotic leak after cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) remains a dreaded complication. There is no consensus statement regarding the optimal timing for bowel anastomoses to perform after or before HIPEC.

Methods: Patients who underwent CRS+HIPEC and had at least one bowel anastomosis were retrospectively analyzed to evaluate if timing of anastomosis done after or before HIPEC had an impact on bowel complication rates (anastomotic leak and perforation).
