RESUMO
BACKGROUND AND OBJECTIVES: The COVID-19 pandemic, with high rate of asymptomatic infections and increased perioperative complications, prompted widespread adoption of screening methods. We analyzed the incidence of asymptomatic infection and perioperative outcomes in patients undergoing cancer surgery. We also studied the impact on subsequent cancer treatment in those with COVID-19. METHODS: All patients who underwent elective and emergency cancer surgery from April to September 2020 were included. After screening for symptoms, a preoperative test was performed from nasopharyngeal and oropharyngeal swabs before the procedure. Patients were followed up for 30 days postoperatively and complications were noted. RESULTS: 2108 asymptomatic patients were tested, of which 200 (9.5%) tested positive. Of those who tested positive, 140 (70%) underwent the planned surgery at a median of 30 days from testing positive, and 20 (14.3%) had ≥ Grade III complications. Forty (20%) patients did not receive the intended treatment; 110 patients were retested in the Postoperative period, and 41 (37.3%) tested positive and 9(22%) patients died of COVID-related complications. CONCLUSION: Routine preoperative testing for COVID-19 helps to segregate patients with asymptomatic infection. Higher complications occur in those who develop COVID-19 in postoperative period. Prolonged delay in surgery after COVID infection may influence planned treatment.

BACKGROUND: The burden of cleft lip and palate (CLP) in the developing world is being tackled by local hospitals and international surgical missions. However, the unmet surgical burden of these conditions is not known, because there are few population-based studies. We conducted this study to find the incidence and prevalence of cleft lip (CL), cleft palate (CP), and CLP and also estimate the unmet burden of these conditions. METHODS: Four blocks comprising of half a million people in the Patan district of Gujarat were chosen as the study areas. This study was conducted over a period of 3 months in 2009. Patients with CL, CP, and CLP were identified by community health workers using snowball sampling method. Data collected included demographics, type of cleft, operated or not, and place of operation. Disability adjusted life years (DALY) was calculated to measure the unmet burden of this disease. RESULTS: The most common among the three conditions was CL (69.4 %). Overall, cleft abnormalities were more common in males (61 %). The overall incidence and prevalence of cleft deformity was 0.73 per 1,000 live births and 0.1 per 1,000 people respectively. The unmet burden of surgical disease of these four blocks was 230 to 494 DALYs. CONCLUSIONS: The incidence of CL with or without palate was found to be 0.7 per 1,000 live births. The large number of unoperated cases (backlog) of cleft deformities suggests a big burden of unmet need in rural India.

Background: Neoadjuvant chemotherapy (NACT) is routinely used in all cases of locally advanced breast cancer and some cases of early breast cancer. We previously reported a pathological complete response (pCR) rate of 8.3%. With the increasing use of taxanes and human epidermal growth factor receptor 2 (HER2)-directed NACT, we conducted this study to understand the current pCR rate and its determinants. Methods: A prospective database of breast cancer patients who underwent NACT followed by surgery between January and December 2017 was evaluated. Results: Of the 664 patients, 87.7% were cT3/T4, 91.6% were grade III, and 89.8% were node-positive at presentation (54.4% cN1, 35.4% cN2). The median age was 47 years; median pre-NACT clinical tumor size was 5.5 cm. Molecular subclassification was 30.3% hormone receptor positive (HR+) HER2-, 18.4% HR+HER2+, 14.9% HR-HER2+, and 31.6% triple negative (TN). Both anthracyclines and taxanes were given preoperatively in 31.2% patients whereas 58.5% of HER2 positive patients received HER2-targeted NACT. The overall pCR rate was 22.4% (149/664), 9.3% in HR+HER2-, 15.6% in HR+HER2+, 35.4% in HR-HER2+, and 33.4% in TN. On univariate analysis, duration of NACT (P < 0.001), cN stage at presentation (P = 0.022), HR status (P < 0.001), and lymphovascular invasion (P < 0.001) were associated with pCR. On logistic regression, HR negative status (Odds ratio [OR] 3.314, P < 0.001), longer duration of NACT (OR 2.332, P < 0.001), cN2 stage (OR 0.57, P = 0.012), and HER2 negativity (OR 1.583, P = 0.034) were significantly associated with pCR. Conclusion: Response to chemotherapy depends on molecular subtype and duration of NACT. A low rate of pCR in the HR+ subgroup of patients warrants reconsideration of neoadjuvant strategies.
RESUMO
BACKGROUND: Treatment of lymph node basins is prognostic and therapeutic for axillary lymph nodes (ALN) as well as internal mammary lymph nodes (IMLNs) in breast cancer. IMLNs can be the first echelon node for the inner/central quadrants of the breast. We evaluated the yield of IMLN dissection (IMLND) mainly in patients with inner and central tumors. METHODS: IMLND was performed in 199 patients between 2000 and 2018, 127 of whom had tumors in the inner/ central quadrants. Clinico-pathological data were retrieved from Electronic Medical Records (EMR). RESULTS: The median age was 50 (range: 24-81). Primary surgery was performed in 82 (41.2%), while 117 (58.8%) were operated post-chemotherapy. Overall, 124/199 (62.3%) had nodes identified in the specimen, more often in primary (61/82, 74.4%) than post-chemotherapy settings (63/117, 53.8%) (P = 0.003). A median of 1 (average: 1.24, range: 0-7) lymph nodes was dissected, and 1 (average: 1.5, range: 1-4) was involved. IMLN was positive in 46/199 (23.1%) patients, not significantly different in primary (21/82, 25.6%) versus post-chemotherapy (25/117, 21.4%) settings (P = 0.545). IMLN was involved in 44.8% of patients with ≥4 involved ALN and 8.2% with uninvolved ALN (P < 0.001). In the absence of ALN involvement and <2cm pT size, 9% of patients had positive IMLN in inner/central quadrant tumors. In univariate analysis, ALN positivity (P < 0.001), pT size (P = 0.023), and grade (P = 0.041) in primary and ALN involvement (P = 0.011) in post-chemotherapy patients were associated with IMLN involvement. On logistic regression, tumor size (OR: 13.914, P = 0.017) and ALN involvement (OR: 11.400, P = 0.005) in primary surgery and ALN involvement (OR: 7.294, P = 0.003) in post-chemotherapy patients correlated with IMLN involvement. CONCLUSIONS: In inner/central quadrant tumors, IMLN is more likely involved with high ALN burden and tumor size >2 cm, whereas those with ≤2cm inner/central quadrant tumors and negative ALN have <10% probability of IMLN involvement.
RESUMO
Importance: Patients with early breast cancer must choose between undergoing breast conservation surgery or mastectomy. This decision is often difficult as there are trade-offs between breast conservation and adverse effects, and women with higher decisional conflict have a harder time choosing the therapy that suits their preferences. Objective: To study the impact of a decision aid with a patient preference assessment tool for surgical decision-making on patients' decisional conflict scale (DCS) score. Design, Setting, and Participants: This 3-group randomized clinical trial was conducted between June 2017 and December 2019 at a single high-volume tertiary care cancer center in Mumbai, India. A research questionnaire comprising 16 questions answered on a Likert scale (from 1, strongly agree, to 5, strongly disagree) was used to measure DCS scores and other secondary psychological variables, with higher scores indicating more decisional conflict. The Navya Patient Preference Tool (Navya-PPT) was developed as a survey-based presentation of evidence in an adaptive, conjoint analysis-based module for and trade-offs between cosmesis, adverse effects of radiotherapy, and cost of mandatory radiation following breast-conserving surgery. Adult patients with histologically proven early breast cancer (cT1-2, N0-1) who were eligible for breast-conserving surgery as per clinicoradiological assessment were included. Those who were pregnant or unable to read the research questionnaire or who had bilateral breast cancer were excluded. Data were analyzed from January to June 2020. Interventions: Patients were randomized 1:1:1 to study groups: standard care including clinical explanation about surgery (control), standard care plus the Navya-PPT provided to the patient alone (solo group), and standard care plus the Navya-PPT provided to the patient and a caregiver (joint group). Main Outcomes and Measures: The primary end point of the study was DCS score. The study was 80% powered with 2-sided α = .01 to detect an effect size of 0.25 measured by Cohen d, F test analysis of variance, and fixed effects. Results: A total of 245 female patients (median [range] age, 48 [23-76] years) were randomized (82 to control, 83 to the solo group, and 80 to the joint group). The median (range) pathological tumor size was 2.5 (0-6) cm. A total of 153 participants (62.4%) had pN0 disease, 185 (75.5%) were hormone receptor positive, 197 (80.4%) were human epidermal growth factor receptor 2 negative, 144 (58.6%) were of middle or lower socioeconomic status, and 114 (46.5%) had an education level lower than a college degree. DCS score was significantly reduced in the solo group compared with control (1.34 vs 1.66, respectively; Cohen d, 0.50; SD, 0.31; P < .001) and the joint group compared with control (1.31 vs 1.66, respectively; Cohen d, 0.54; SD, 0.31; P < .001). Conclusions and Relevance: The results of this study demonstrated lower decisional conflict as measured by DCS score following use of the online, self-administered Navya-PPT among patients with early breast cancer choosing between breast-conserving surgery vs mastectomy.

Breast cancer is no longer considered a single disease, and with better understanding of cancer biology, its management has evolved over the years, into a complex individualized use of therapeutics based on variable expressions of predictive and prognostic factors. With the advent of molecular and genetic research, the complexity and diversity of breast cancer cells and their ability to survive and develop resistance to treatment strategies became more evident. At the same time, targeted therapies evolved, as specific targets were discovered such as HER2 receptor, and androgen receptor. More recent is the development of immunotherapy which aims at strengthening the host immune system to identify and kill the tumor cells. In breast cancer treatment, use of molecular tests has been a target of controversies, due to their high costs and inaccessibility in limited resource situations. Research in breast cancer is also proceeding at a rapid pace, but it is important to remember that breast cancer continues to be a complex interplay of alterations at molecular and genetic level, with the variability in expressions at protein level leading to difference in behavior and responses to treatment and overall outcome. In the succeeding paragraphs, we will try to review the available evidence in literature and attempt to understand the molecular complexity of breast cancer in order to simplify the art of treating the disease and improving outcomes.
RESUMO
INTRODUCTION: Surgery is the primary treatment of phyllodes tumor of the breast, and margins are the most important risk factor associated with local recurrence. We conducted a retrospective audit of 433 patients treated at our center. PATIENTS AND METHODS: Women who presented with phyllodes tumors between 1999 and 2017 were included in the analysis. Data was collected from the hospital medical records, telephonic interviews, and electronic mail. RESULTS: Of the 433 women included in this study, 177 (40.9%) had benign phyllodes tumors, 84 (19.4%) were borderline, 131 (30.3%) were malignant, and 41 (9.5%) had sarcoma. A history of previous excision was noted in 154 (35.6%) patients, of which 104 presented with local recurrence. Of the total patients, 209 (48.3%) underwent breast conservation surgery; the median pT was 6 cm. At a median follow-up of 37.9 months, the 5-year disease-free survival (DFS) was 82.9%. On multivariate analysis, the factors that impacted DFS were histology (hazard ratio, 4.1; 95% confidence interval [CI], 1.5-10.9; P = .005) and history of previous excision biopsy (hazard ratio, 3.39; 95% CI, 1.76-6.52; P < .001). We analyzed 231 women who presented without any prior excision separately, wherein at a median follow-up of 44.1 months, the DFS was 92.1% (95% CI, 92.05%-92.15%). In addition, less recurrences were noted in this cohort (5.6% [13/231] in no-excision biopsy vs. 12.5% with surgery done prior to presentation to our institute). CONCLUSION: A previous history of excision and the histologic subtype of phyllodes tumor are factors that have an impact on DFS, thus emphasizing the need for appropriate surgical planning and en bloc excision of the phyllodes at presentation.

AIM: To assess the usefulness of single-staged posteriorly based dorsal tongue flap in oral cavity reconstruction following ablative surgery, in terms of flap viability, functional outcome and donor site morbidity. MATERIALS AND METHODS: A prospective database of patients who were reconstructed with dorsal tongue flap between July 2006 and November 2010 was used. RESULTS: There were 27 patients who had tongue flap reconstruction in this period. Size of the defect following excision ranged from 3.5-5 cm in greatest dimension. Marginal mandibulectomy was done in thirteen patients and in twelve patients mucoperiosteal stripping was done. There was no partial or total flap loss in our series. Two patients had minor salivary leak which was managed conservatively. All the patients had adequate mouth opening, good swallowing and speech following surgery. CONCLUSION: Dorsal tongue flap is a simple and reliable flap for intra oral reconstruction. It provides good functional results without much morbidity.

OBJECTIVES: The technology and resource-rich solutions of the developed world may not be completely applicable to or replicable in disasters occurring in the developing world. With the current looming hazards of pandemics, climate change, global terrorism and conflicts around the world, policy makers and governments will need high-quality scientific data to make informed decisions for preparedness and mitigation. The evidence on disasters in peer-reviewed journals about the developing world was examined for quality and quantity in this systematic review. METHODS: PubMed was searched using the Medical Subject Heading (MeSH) terms disasters, disaster medicine, rescue work, relief work, and conflict and then refined using the MeSH term developing country. The final list of selected manuscripts were analyzed by type of article, level of evidence, theme of the manuscript and topic, author affiliation, and region of the study. RESULTS: After searching and refining, <1% of the citations in PubMed addressed disasters in developing countries. The majority was original research articles or reviews, and most of the original research articles were level IV or V evidence. Less than 25% of the authors were from the developing world. The predominant themes were missions, health care provision, and humanitarian aid during the acute phase of disasters in the developing world. CONCLUSIONS: Considering that 85% of disasters and 95% of disaster-related deaths occur in the developing world, the overwhelming number of casualties has contributed insignificantly to the world's peer-reviewed literature. Less than 1% of all disaster-related publications are about disasters in the developing world. This may be a publication bias, or it may be a genuine lack of submissions dealing with these disasters. Authors in this part of the world need to contribute to future disaster research through better-quality systematic research and better funding priorities. Aid for sustaining long-term disaster research may be a more useful investment in mitigating future disasters than short-term humanitarian aid missions to the developing world.

Tuberculosis of the oral cavity is a rare condition. A 55-year-old labourer was referred as a case of oral cancer for further management. The patient had no systemic symptoms. Biopsy of the lesion revealed caseating granulomatous inflammation. Chest X-ray and sputum revealed evidence of asymptomatic pulmonary tuberculosis. The purpose of this paper is to sensitize clinicians to consider oral tuberculosis as a differential diagnosis in patients with an Non-healing oral cavity ulcer.
