Objective: To evaluate the specific oncologic significance of the lateral margin (LM)- the marginal plane closest to skin- in resected buccal cancer., Materials and Methods: 216 consecutive, treatment naïve patients undergoing primary surgery for buccal cancer were included. Cheek skin was resected based on clinical features of skin or subcutaneous involvement or proximity to oral commissure. Main outcomes were 1) frequency of LM ≤1 mm in relation to other (anterior, posterior, superior and inferior) margins and 2) association of LM ≤1 mm with LRFS and DFS. Secondary outcomes were rate of LM ≤1 mm and size of LM with and without skin resection., Results: A total of 67 (31 %) patients had one or more margin ≤1 mm, of which LM comprised 36 (54 %). LM ≤1 mm was disproportionately highest among the five marginal planes (p < 0.001) and was independently associated with LRFS and DFS. Both associations held in sensitivity analysis wherein patients with co-existent margin ≤1 mm at any of the other four marginal planes underwent group-wise exclusion. Skin resection and preservation was performed in 61 (28 %) and 155 (72 %) patients respectively. The latter had a higher rate of LM ≤1 mm and smaller LM size (both p < 0.05)., Conclusions: This cohort study of buccal cancer shows that LM is most prone for ≤1 mm size. LM ≤1 mm predicts worse LRFS and DFS independent of other margins and risk factors. As skin preservation is associated with a higher rate of LM ≤1 mm, surgeons must lower the threshold to encompass more tissue laterally, including skin where appropriate., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 Elsevier Ltd.

Objective: To assess the prognostic importance of margin in resected buccal cancer within a framework of risk factor-driven postoperative adjuvant treatment., Materials and Methods: Consecutive, treatment naïve patients undergoing primary surgical treatment for buccal cancer. Margin was defined as clear (≥5 mm), close (1-4 mm) and involved (<1 mm). Main outcome was association of margin with local recurrence free survival (LRFS). Subgroup analysis of close margin was performed according to receipt or no receipt of adjuvant treatment. A numerical margin cut-off in mm that could independently predict LRFS was sought to be identified., Results: Of the 167 patients included, the frequency of clear, close and involved margins was 50 (30 %), 78 (47 %) and 39 (23 %) respectively, among whom 52 %, 44 % and 98 % received postoperative adjuvant treatment respectively. Clear and close margins had similar 3-year LRFS (89 % and 96 % respectively), while involved margin had worse 3-year LRFS at 65 %. Involved margin was confirmed to be strongly and independently associated with worse LRFS. Within close margin, receipt and no receipt of adjuvant treatment had similar 3-year LRFS (92 % and 100 % respectively). A margin cut-off of 2 mm was identified at or above which LRFS approximated that of clear margin., Conclusions: This single center cohort study of patients with resected buccal cancer suggests that close margin is distinct from and has a better LRFS than involved margin. A subset of close margin, with margin size ≥ 2 mm and no other adverse features, might be spared adjuvant treatment without compromising outcomes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

A previous report from the Indian HIPEC registry showed acceptable early survival and morbidity in patients undergoing cytoreductive surgery (CRS) + / - hyperthermic intraperitoneal chemotherapy (HIPEC). The goal of this retrospective study was to evaluate the long-term outcomes in these patients. Three hundred seventy-four patients treated from December 2010 to December 2016 and enrolled in the Indian HIPEC registry were included. All patients had completed 5 years from the date of surgery. The 1-, 3-, 5- and 7-year progression-free (PFS) and overall survival (OS) and factors affecting these were evaluated. The histology was epithelial ovarian cancer in 209 (46.5%), pseudomyxoma peritonei (PMP) in 65 (17.3%) and colorectal cancer in 46 (12.9%) patients. The peritoneal cancer index (PCI) was ≥ 15 in 160 (42.8%). A completeness of cytoreduction (CC) score of 0/1 resection was obtained in 83% (CC-0-65%; CC-1-18%). HIPEC was performed in 59.2%. At a median, follow-up of 77 months (6-120 months), 243 (64.9%) patients developed recurrence, and 236 (63%) died of any cause; 138 (36.9%) were lost to follow-up. The median OS was 56 months (95% CI 53.42-61.07), and the median PFS was 28 months (95% CI 37.5-44.4). The 1-, 3-, 5- and 7-year OS was 97.6%, 63%, 37.7% and 24% respectively. The 1-, 3-, 5- and 7-year PFS was 84.8%, 36.5%, 27.3% and 22% respectively. The use of HIPEC ( p  = 0.03) and PMP of appendiceal origin ( p  = 0.01) was independent predictors of a longer OS. CRS + / - /HIPEC may achieve long-term survival in patients with PM from different primary sites in the Indian scenario. More prospective studies are needed to confirm these findings and identify factors influencing long-term survival., Supplementary Information: The online version contains supplementary material available at 10.1007/s13193-023-01727-7., Competing Interests: Conflict of InterestThe authors declare no competing interests., (© The Author(s), under exclusive licence to Indian Association of Surgical Oncology 2023.

Objectives: To compare clinical outcomes following total and selective peritonectomy performed during interval cytoreductive surgery (CRS) for stage IIIC/IVA serous epithelial ovarian cancer., Methods: In this retrospective study, extent of peritonectomy was classified as total parietal peritonectomy (TPP) which comprised of removal of the entire parietal peritoneum and the greater and lesser omenta or selective parietal peritonectomy (SPP) that included 1/>1 of parietal peritonectomies performed to resect sites of residual disease. A comparison of patient and disease characteristics, morbidity, mortality and survival outcomes between the two groups was made., Results: From January 2013 to December 2017, 79 patients underwent CRS (TPP-30, SPP-49) with or without intraperitoneal chemotherapy (IPC). The median PCI was 14 for TPP and 8 for SPP. The 90-day grade 3-4 morbidity (23.3% for TPP, 14.2% for SPP, p = 0.58) the 90-day mortality was similar (p = 0.58). The median disease free survival (DFS) was 37 months for SPP and 33 months for TPP (p = 0.47) and median overall survival (OS) not reached for both. The 3-year OS was 95% for TPP and 70.8% for SPP (p = 0.06). The only independent predictor of OS was grade 3-4 morbidity (p = 0.01) and not TPP (p = 0.09). Microscopic residual disease was seen in 23.3% with normal looking peritoneum in TPP group., Conclusions: TPP was not associated with increased morbidity compared to SPP. There was a trend towards a longer OS in the TPP group and the finding of residual disease in 'normal looking' peritoneum' warrants prospective evaluation of the benefit of TPP in this setting., (Copyright © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Objectives: The goals were to study • The pattern of pathological response to neoadjuvant chemotherapy (NACT) and its clinical implications • The impact of chemotherapy response grade (CRG) on survival METHODS: A retrospective analysis of patients undergoing interval cytoreductive surgery (CRS) between January 2013 to December 2017 was performed. The surgical and pathological reports were analyzed and surgical and pathological PCI compared. The pathological response to chemotherapy was assessed using the score developed by Bohm. et al., Results: In 79 patients, it was observed that sites involved by disease first like ovaries and pelvic peritoneum (lower region) were the last to respond preceded by the omentum, right upper quadrant (RUQ) peritoneum (upper region) and parietal peritoneum (middle region). Microscopic residual disease was seen in 20.2% in normal looking areas of peritoneum and in 20% with no gross residual disease in the RUQ. Visual inspection during surgery overestimated the disease extent in 40.5% and underestimated it in 15.1%. There was no difference in the progression free (p = 0.587) and overall survival (p = 0.157) between patients with CRG 1, 2 and 3 (poor, moderate, and complete/near complete response, respectively). Retroperitoneal nodes were positive in 0% with CRG 3, 27.5% with CRG 2 and 72.7% with CRG 1 (p < 0.0001)., Conclusions: The pathological response to NACT follows a specific pattern. Visual inspection is of limited value in assessing disease extent following NACT. Surgery following NACT should target sites involved before NACT and not just residual disease. The response in regional nodes should be included in chemotherapy response scores., (Copyright © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

To determine factors influencing failure-to-rescue in patients with complications following cytoreductive surgery and HIPEC. A retrospective analysis of patients enrolled in the Indian HIPEC registry was performed. Complications were graded according to the CTCAE classification version 4.3. The 30- and 90-day morbidity were both recorded. Three hundred seventy-eight patients undergoing CRS with/without HIPEC for peritoneal metastases from various primary sites, between January 2013 and December 2017 were included. The median PCI was 11 [range 0-39] and a CC-0/1 resection was achieved in 353 (93.5%). Grade 3-4 morbidity was seen 95 (25.1%) at 30 days and 122 (32.5%) at 90 days. The most common complications were pulmonary complications (6.8%), neutropenia (3.7%), systemic sepsis (3.4%), anastomotic leaks (1.5%), and spontaneous bowel perforations (1.3%). Twenty-five (6.6%) patients died within 90 days of surgery due to complications. The failure-to-rescue rate was 20.4%. Pulmonary complications ( p  = 0.03), systemic sepsis ( p  < 0.001), spontaneous bowel perforations ( p  < 0.001) and PCI > 20 ( p  = 0.002) increased the risk of failure-to-rescue. The independent predictors were spontaneous bowel perforation ( p  = 0.05) and systemic sepsis ( p  = 0.001) and PCI > 20 ( p  = 0.02). The primary tumor site did not have an impact on the FTR rate ( p  = 0.09) or on the grade 3-4 morbidity ( p  = 0.08). Nearly one-fifth of the patients who developed complications succumbed to them. Systemic sepsis, spontaneous bowel perforations, and pulmonary complications increased the risk of FTR and multidisciplinary teams should develop protocols to prevent, identify, and effectively treat such complications. All surgeons pursuing this specialty should perform a regular audit of their results, irrespective of their experience., Competing Interests: Compliance with Ethical StandardsThe authors declare that they have no conflicts of interest.

HIPEC in addition to interval CRS has shown a survival benefit of 12 months compared to CRS alone. However, there are many controversial issues pertaining to CRS itself which should be addressed first. To compare NACT and primary CRS approaches when CRS is categorized according to the extent of resection. To evaluate the feasibility of performing HIPEC at these two time points. A retrospective analysis of patients with stage III C ovarian cancer undergoing primary and interval CRS + HIPEC was performed. The surgical approach for interval CRS was classified as (1) resection of sites of residual disease alone or (2) resection of sites involved before NACT. The morphological response was divided into different categories, and surgeons had to state what they consider residual disease and what they do not. From January 2013 to December 2017, 54 patients were included (18-primary; 36-interval). Median PCI 11 vs 6.5 ( p  = 0.07); CC-0 was obtained in 77.7%. Three surgeons resected previously involved sites; three sites of residual disease only. All surgeons resected areas of scarring. Twenty percent patients had residual disease in "normal-looking" peritoneum. Morbidity ( p  = 0.09), median OS ( p  = 0.71), and median DFS ( p  = 0.54) were similar in the two groups. Early recurrence occurred in 50% with resection of residual disease alone compared to 16.6% when previous disease sites were resected ( p  = 0.07). Interval CRS should be performed to resect sites involved prior to NACT and not just sites of residual disease. HIPEC can be performed in both primary/interval settings with acceptable morbidity., Competing Interests: Compliance with Ethical StandardsThe authors declare that they have no conflict of interest.

Infectious endophthalmitis is an important cause of vision loss worldwide. This entity most often occurs as a complication of intraocular surgery especially following cataract surgery or intravitreal injection. Endophthalmitis is regarded as a serious complication following ocular surgery and the final visual outcome is fundamentally contingent on timely recognition and intervention. Intravitreal and oral antibiotics in combination with pars plana vitrectomy or vitreous aspiration remain the mainstay in the management of endophthalmitis. However, significant inflammation may persist even after sterilization of the intraocular cavities with appropriate antibiotics resulting in failure of treatment. This forms the basis for the use of intravitreal corticosteroids as an adjuvant to antibiotics in the management of infectious endophthalmitis. In the index manuscript, we review the existing literature to determine the role of intravitreal corticosteroids as an adjuvant to antibiotics in treating infectious endophthalmitis, and discuss their beneficial effects and controversial concerns.

Background: The Indian HIPEC registry is a self-funded registry instituted by a group of Indian surgeons for patients with peritoneal metastases (PM) undergoing surgical treatment. This work was performed to  • Evaluate outcomes of cytoreductive surgery ± HIPEC in patients enrolled in the registry.  • Identify operational problems., Methods: A retrospective analysis of patients enrolled in the registry from March 2016 to September 2017 was performed. An online survey was performed to study the surgeons' attitudes and existing practices pertaining to the registry and identify operational problems., Results: During the study period, 332 patients were enrolled in 8 participating centres. The common indication was ovarian cancer for three centres and pseudomyxoma peritonei for three others. The median PCI ranged from 3 to 23. A CC-0/1 resection was obtained in 94.7%. There was no significant difference in the morbidity (p = .25) and mortality (p = .19) rates between different centres. There was a high rate of failure-to-rescue (19.3%) patients with complications and the survival in patients with colorectal PM was inferior. A lack of dedicated personnel for data collection and entry was the main reason for only 10/43 surgeons contributing data. The other problem was the lack of complete electronic medical record systems at all centres., Conclusions: These results validate existing practices and identify country-specific problems that need to be addressed. Despite operational problems, the registry is an invaluable tool for audit and research. It shows the feasibility of fruitful collaboration between surgeons in the absence of any regulatory body or funding for the project.

There are various registries for patients with peritoneal metastases (PM) that aid pooling of data and generate evidence that dictates current clinical practice. This manuscript describes the setting up of the Indian HIPEC registry that was set up with a similar goal by a group of Indian surgeons. This is a registry for patients with PM treated with CRS and HIPEC in India. It also acts as a database for storing treatment-related information. Patients with PM from colorectal ovarian, gastric, appendiceal tumors, and other rare peritoneal tumors/metastases from rare tumors are enrolled in the registry. A coordinator updates the disease status of patients on a yearly basis. A private organization maintains the database. A non-disclosure agreement is signed between the company and each surgeon contributing to the registry to maintain confidentiality. For enrolling patients, securing institutional permission depends on the requirement of each institute; patient consent is mandatory. Data entry can be prospective or retrospective. To propose and conduct a study, the approval of a scientific committee linked to the registry is required. The Indian HIPEC registry is a practical database for Indian surgeons. There is no regulatory body that mandates collection and publication of scientific data in India. The onus is on each surgeon to capture valuable information pertaining to these common and rare diseases that could contribute to the existing scientific knowledge and guide the treatment of these patients in the future. The next challenge will be to enter data into the registry.

Worldwide, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been used for nearly 3 decades to treat peritoneal metastases (PM), improve quality of life, and prolong survival substantially in selected patients. In India, the use of the combined modality of treatment dates back a decade with majority of the efforts taking place within the last 5 years. The first PSOGI workshop (India) held in April 2015, at Bangalore, India offered an opportunity for Indian surgeons performing CRS and HIPEC to share their experience. To study the methodologies of CRS and HIPEC (hospital set up, equipment, training and surgical background) as well as the outcomes in terms of perioperative morbidity and mortality and short and long term survival of patients treated in India, Indian surgeons who had treated at least 10 patients with this combined modality were invited to present their experience. Data collection was retrospective. Analysis of the pooled data was carried out. Eight surgeons treated 384 patients with CRS and HIPEC over a period of 10 years. The commonest primary sites were ovary (as first line therapy n = 124), followed by appendix, including pseudomyxoma peritonei (n = 99), colorectum (n = 77), recurrent ovary (as second line therapy, n = 33), stomach (n = 15), primary peritoneal cancer (n = 10), peritoneal mesothelioma (n = 9) and rare tumors in 17 patients. The weighted mean PCI for all 384 patients was 18.25. 349/384 patients (90.88 %) had a complete cytoreduction (completeness of cytoreduction score of CC-0/1). Grade 3-5 complications developed in 108 patients (27.34 %) and 30 day mortality occurred in 28 (7.29 %) patients. This study showed that CRS and HIPEC can be performed with an acceptable morbidity and mortality in Indian patients. Most of the surgeons are on the learning curve and further improvement in these outcomes is expected over a period of time. Pooling of data related to both common and rare peritoneal cancers would be useful in knowing the disease behavior, response to treatment and outcomes in Indian patients. The 2015 PSOGI meeting provided a unique platform for data presentation with feedback from international experts in the field of peritoneal surface oncology. Future meetings are planned to expand the evaluation of Indian data and progress.

Differentiated thyroid cancer is, usually, associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual. Only few cases of papillary carcinoma with axillary nodal metastasis were previously reported in the literature. We present a 38-year-old female who underwent Iodine-131 whole-body scintigraphy, after total thyroidectomy and bilateral neck lymph node dissection for papillary carcinoma of thyroid, showed intense uptake in the remnant thyroid, lung metastasis, left cervical and left axillary lymph nodes. Excision of left axillary lymph nodes confirmed metastatic papillary carcinoma.

Ectopic thyroid tissue primarily occurs along the course of the embryologic migration of the thyroid gland. Mediastinal thyroid may be differentiated into primary and secondary form. Primary mediastinal goiters are quite rare, occurring in <1% of all goiters. We present findings of 29-year-old female, case of papillary carcinoma of the thyroid who underwent iodine-131 whole body scintigraphy after total thyroidectomy showed a primary mediastinal mass lesion along with residual thyroid. She underwent mediastinal mass excision through sternotomy and biopsy confirmed as ectopic nodular colloid goiter with no malignancy.

Pulmonary sclerosing hemangioma (PSH), or the alternative name of "sclerosing pneumocytoma," is a rare benign neoplasm. PSH is often asymptomatic and presents as a solitary or multiple pulmonary nodules on radiologic imaging studies. Few articles have been reported to describe the fluorodeoxyglucose positron emission tomography (FDG PET) findings about PSH. The authors describe an interesting but uncommonly encountered cause of false positive FDG PET scan in the thorax in a 25-year-old woman, a known case of arteriovenous malformation of oral cavity who underwent embolization and presented with incidental detection of bilateral lung nodules. She is asymptomatic and is on follow-up.

Purpose: To estimate the prevalence of posterior embryotoxon (PE) in the general ophthalmic clinic and to identify any features of PE that suggest that it is pathological rather than physiological., Methods: Over 700 consecutive patients of all ages were examined with the slit lamp during their routine eye clinic appointment. Patients with posterior embryotoxon were invited to return for full ocular examination including keratometry, corneal topography, and gonioscopy., Results: In all, 49 out of 723 patients were found to have PE. This gives a prevalence of 6.8% with an age range of 18 months to 95 years. There was a higher prevalence in the younger age group of 22.5% (age range 18 months to 20 years) compared to 5.9% in the older age range (21-95 years). A total of 29 patients with PE returned for further examination. Six patients had glaucoma (two with Axenfeld's syndrome and one with aniridia), and one had ocular hypertension. In all, 20 patients had bilateral PE on slit-lamp examination, which increased to 24 with gonioscopy. The majority of the PE was seen temporally (97.9%) and limited to a few clock hours. Gonioscopy showed that eight patients with PE had associated inferior pigmentation of schwalbes line., Conclusion: This large series found the prevalence of PE the general ophthalmic clinic to be 6.8%. Its presence should prompt careful anterior segment examination, including gonioscopy, to identify any associated abnormalities that may carry a risk of glaucoma. Children should also be assessed for any associated systemic or genetic abnormality.
