Ipsilateral Cervicodeltopectoral Flap: A Forgotten Technique, Revival in the Era of Microvascular Reconstruction.

Oral cavity cancer is one of the most common cancers in India responsible for significant morbidity and mortality in Indian subcontinent. Majority of cases present in advanced stages which requires extensive reconstruction following tumor resection. Microvascular free flap reconstruction is now considered standard of care for reconstruction for major head and neck skin-mucosal defects but, many factors still act as hindrance like patient's comorbidities, long operating hours for microvascular reconstruction, logistic and financial issues from patient's side. In such situation it is better to have a backup plan for reconstruction of major head and neck defects using pedicled flaps. Pectoralis major myocutaneous (PMMC) flap has been the workhorse flap for head and neck reconstruction since its introduction four decades ago. But relying too much on PMMC flap for major skin-mucosal defects especially in female patients is associated with complications and risk for flap failure leading to catastrophic and significant patient morbidities. Our study involves the use of two flaps for head and neck reconstuction involving skin-mucosal defects i.e PMMC flap for mucosal defect and cervicodeltopectoral (CDP) flap for skin defect. As of now there has been no retrospective or prospective study done which has given a conclusive statement regarding use of these two flaps simultaneously for head and neck reconstruction to the best of our knowledge. In our experience from the present study, CDP flap offers an excellent alternative for extensive head and neck reconstruction and can be readily included in the surgeon's armamentarium with proper planning and meticulous handling.

Complete mesocolic excision for right colon cancer: Is D3 lymphadenectomy necessary?

AIM: Although complete mesocolic excision (CME) for colon cancer is oncologically sound, to date, there has been no consensus on the extent of lymphadenectomy in radical right colectomy. This study essentially compared the perioperative and survival outcomes of CME with two templates of lymphadenectomy for right colon cancer. METHOD: This was a propensity matched, retrospective analysis of a single centre, prospectively maintained database of all patients undergoing elective right colectomy for nonmetastatic, biopsy-proven adenocarcinoma from November 2013 to October 2018. CME + D3 was adopted selectively, documented prospectively, and compared with patients undergoing CME + central vascular ligation (CVL). The only technical difference between the groups was the excision of the surgical trunk of Gillot in the CME + D3 group. Postoperative, long-term outcomes and patterns of recurrence were compared between the groups. RESULTS: Of the 244 eligible patients, 88 (36.1%) and 156 (63.9%) underwent CME + D3 and CME + CVL, respectively. Matched groups (72 [CME + D3] vs. 108 [CME + CVL]) showed no difference in histology, tumour grade, postoperative complications, mortality, and hospital stay. CME + D3 was preferentially performed laparoscopically (35.2% vs. 9%), was associated with lower blood loss (215 mL vs. 297 mL, p = 0.001), higher nodal yield (31 vs. 25 nodes, p = 0.003) and a higher incidence of chyle leak (4 vs. 0, p = 0.013). At a median follow-up of more than 57 months, there was no significant difference in local recurrence, disease-free or overall survival. CONCLUSION: In this retrospective study, lymphadenectomy along the superior mesenteric vein, as a component of CME for right colon cancer, offered a higher nodal yield with no improvement in oncological outcome. Dissection of the SMV, over and above a D2 dissection, could therefore be restricted to specialized colorectal units until further studies establish the incremental oncological benefit of this extended lymphadenectomy or define a patient group in whom it is beneficial.

To CT or not to CT: Questioning the Cost-Effectiveness of CT Thorax in Head and Neck Cancers.

Computed tomography (CT) scan has been an integral part of the diagnostic workup for patients with head and neck squamous cell carcinoma. Our study was designed to find out the incidence of distant metastasis and second primary tumor and to correlate the cost-effectiveness of CT thorax in detecting the same. This study was conducted among 326 cancer patients who visited our center with curative intent in the year 2021, with lesions in various head and neck subsites. Data were collected based on their pathological TNM staging and the presence of distant metastasis as evident on their CT thorax imaging with various variables related to the disease. Incremental cost-effectiveness ratio (ICER) was calculated for detecting a single metastatic deposit and second primary tumor in terms of Indian currency and was correlated to each subsite and stage of disease at presentation. Out of these 326 patients, 281 patients were included in our study after considering the inclusion criteria, and among these 281 patients, 235 of them underwent CT thorax for metastatic workup. No patient was found to have a second primary. Metastases were found in 12 patients. The site of primary lesion and clinical tumor (cT) staging were found to be significantly influencing the incidence of metastasis on CT thorax. ICER was least for larynx, pharynx, and paranasal sinuses and was highest for oral cavity primaries and early-stage disease. As per our observations and results of ICER, CT thorax is indeed a valuable modality but should be used judiciously when it comes to initial diagnostic workup.

A Mechanistic Review of Methotrexate and Celecoxib as a Potential Metronomic Chemotherapy for Oral Squamous Cell Carcinoma.

The combination of low-dose methotrexate and celecoxib as metronomic chemotherapy (MCT) is a novel therapy, believed to act by modulating the immune response, inhibiting angiogenesis and its cytotoxic action, though the exact mechanism of action is unclear. Clinically, MCT was found to be very effective in delaying tumor progression in patients with head and neck squamous cell carcinoma in both curative and palliative settings. This review was aimed to give a brief insight into the mechanism of action and potential molecular alterations of MCT in the treatment of oral cancers taking into consideration the various in vivo and in vitro studies.

Cancer care continuum at a tertiary care centre in India during the Covid-19 pandemic and nationwide lockdown: Healthcare delivery through telemedicine.

Background The Covid-19 pandemic and subsequent lockdown in India caused disruptions in cancer treatment due to the restriction on movement of patients. We aimed to maintain continuity in cancer treatment during the lockdown through teleconsultations. We tried to reach out to our patients using telephonic consultations by establishing a Teleconsult Centre facility run by a team of doctors and patient navigators. Methods We telephonically contacted all patients who had outpatient appointments from 23 March to 30 April 2020 at our centre through the Teleconsult Centre to understand their current circumstances, feasibility of follow-up, local resources and offered best possible alternatives to continue cancer treatment, if required. Results Of the 2686 patients scheduled for follow-up during this period, we could contact 1783 patients in 9 working days. Through teleconsultations, we could defer follow-ups of 1034 patients (57.99%, 95% confidence interval [CI] 55.6%-60.3%), thus reducing the need for patients to travel to the hospital. Change in systemic therapy was made in 75 patients (4.2%, 95% CI 3.3%-5.2%) as per the requirements and available resources. Symptoms suggestive of disease progression were picked up in 12 patients (0.67%, 95% CI 0.35%-1.17%), who were advised to meet local physicians. Conclusion Our study suggests that the majority of patients on follow-up can be managed with teleconsultation in times of crisis. Teleconsultation has the potential of being one of the standard methods of patient follow-up even during periods of normalcy.

Signet ring cell cancer of stomach and gastro-esophageal junction: molecular alterations, stage-stratified treatment approaches, and future challenges.

PURPOSE: There has been an increase in the incidence of signet ring cell cancer (SRCC) of the stomach and gastro-esophageal junction (GEJ). The multistage carcinogenesis involving genetic and epigenetic aberrations may have a major role in the increasing incidence of SRCC. Although there are numerous studies on the prognostic value of SRCC, they are markedly inconsistent in their results, making it impossible to draw any meaningful conclusions. We aimed to examine the available evidences on molecular alterations and stage-stratified treatment approaches in SRCC of the stomach and GEJ. METHODS: A systematic search was carried out in PubMed. Studies available in English related to SRCC of stomach and gastro-esophageal junction were identified and evaluated. RESULTS: This study reviewed the current evidence and provided an insight into the molecular alterations, stage-stratified treatment approaches, and future challenges in the management of SRCC of the stomach and GEJ. Specific therapeutic strategies and personalized multimodal treatment have been recommended based on the tumor characteristics of SRCC. CONCLUSION: Multistage carcinogenesis involving genetic and epigenetic aberrations in SRCC is interlinked with stage-dependent prognosis. Specific therapeutic strategy and personalized multimodal treatment should be followed based on the tumor characteristics of SRCC. Endoscopic resection, radical surgery, and perioperative chemotherapy should be offered in carefully selected patients based on stage and prognostic stratification. Future studies in genetic and molecular analysis, histopathological classification, and options of multimodality treatment will improve the prognosis and oncological outcomes in SRCC of gastric and GEJ.

The contralateral based Cervico-pectoral rotation flap for large neck defects.

PURPOSE: We here describe our technique of contralateral based cervico-pectoral (CCP) flap for the reconstruction of large neck defect following resection of primary tumour or recurrence particularly due to the lymph node mass. METHODS: The study included the patients who underwent major head and neck surgical ablative procedures followed by CCP flap reconstruction between July 2020 and November 2020. Patients were kept on rigorous regular follow-up to evaluate for flap related complications like flap necrosis, flap dehiscence and oro-cutaneous fistula. Among the 5 patients included and presented in the series, 2 patients were salvage cases post adjuvant treatment. RESULTS: Five patients who have undergone head and neck reconstruction using CCP flap were included. No major flap related complications occurred in post-operative period. CONCLUSION: The CCP flap is simple to perform and reproducible and can be added to the armamentarium for the reconstruction of large upper neck defect following resection of primary tumour or recurrence involving the cervical skin in resource limited setting and in contraindication for microvascular reconstruction. Proper planning, meticulous dissection and adequate release or rotation and tension free closure would provide best outcomes.

A Survey of Personnel Protective equipment's (PPE) Use and Comfort Levels Among Surgeons During Routine Cancer Surgery in the COVID-19 Pandemic.

Personnel protective equipment (PPE) are recommended during surgery even in COVID-19 negative patients especially in a high-prevalence region due to its higher false-negative rates. However, the use of PPE has not been universal mainly due to the perception of discomfort and associated stress and fatigue. This study was done to understand the pattern of PPE use by cancer surgeons during the pandemic and the associated discomfort, stress, and fatigue with its use. The survey, consisting of 29 questions, was circulated widely across the country by email and chat groups among cancer surgeons. The study was registered with the Clinical Trials Registry of India (CTRI/2020/08/027050). We received a total of 342 evaluable responses that could be included for analysis. All the respondents used appropriate PPE in different combinations. N-95 mask and the face shield were the two components of the PPE that gave rise to a lot of discomforts. Fogging (of face shields) (p < 0.001,OR 3.61), dryness of mouth (p < 0.001,OR 3.35), and breathing difficulty/feeling of suffocation (p = 0.034,OR 1.68) contributed to the stress, whereas headache (p < 0.001,OR 11.34) and breathing difficulty/feeling of suffocation (p < 0.001,OR 4.24) contributed to the fatigue associated with PPE use the most. PPE was routinely used during cancer surgery in COVID-19 negative patients during the pandemic. However, most surgeons experienced different degrees of discomfort, especially with the N-95 masks and eye protection.

Compliance and perception about personal protective equipment among health care workers involved in the surgery of COVID-19 negative cancer patients during the pandemic.

BACKGROUND: Health care workers (HCWs) are at risk of getting infected while at work, for example, operating room (OR), hence it is pertinent that they don all the appropriate personal protective equipment (PPE) to minimize the chance of getting infected. METHODS: A COVID-19 specific briefing and debriefing form was created and used in the OR along with the World Health Organization surgical safety checklist to reinforce the use of appropriate PPE. An audit was subsequently done to understand the compliance to PPE use, followed by a survey based on the findings of the audit to understand the issues related to noncompliance. RESULTS: The form was used in 183 out of the 238 (77%) surgeries performed during a months' time. The overall compliance for PPE usage was 96.3%. Noncompliance was seen most often for eye protection (45/567) (P = .01). The survey revealed that this was mostly among surgeons mainly due to discomfort, poor visibility, and frequent fogging. CONCLUSIONS: Our HCW were adapting well to the new normal of donning appropriate PPE in the OR, except for the eye protection due to discomfort and visibility related issues. This is important to know so that necessary changes could be introduced to better the compliance.

Asymptomatic Cardiac Metastasis in a Diagnosed Case of Squamous Cell Carcinoma of the Middle Third of Esophagus.

A lady walks in with complaints of dysphagia mostly to solids to begin with and gradually progressive to liquids requiring naso-gastric tube feeding, with history of vomiting after taking food and weight loss of 20kilograms over 2months. Upper gastrointestinal endoscopy showed an ulceroproliferative growth starting at 28cms from the central incisor and extending upto 36 cms with luminal compromise. Biopsy from the lesion was found to be moderately differentiated squamous cell carcinoma. As part of metastatic work-up a PET-CT (Figure 1 shows lesion in the left ventricle) was done which revealed a metabolically active lesion involving the lower third of esophagus and a metabolically active lesion in the wall of the left ventricle which was the only site of metastatic diseae(Figure 2. Maximum intensity projection). Further investigations were done for characterisation of the cardiac lesion. 2-D Echo cardiography was done and was normal with an ejection fraction of 60%. A cardiac MRI was done which showed a soft tissue mass in the wall of the left ventricle which was isointense with normal myocardium and hyperintense on double inversion recovery sequence which measured 3.2 x 3 cms with post contrast enhancement. She was planned for palliative radiotherapy. A total dose of 30Gy in 10 fractions over 2 weeks was delivered. She tolerated the treatment well with Grade I mucositis (as per RTOG grading) and on follow-up after 4 weeks she had 40% relief in dysphagia and could take semi-solid food with little difficulty.

Splenic Metastasis from Cancer of Uterine Cervix-a Rare Case.

Cancer of uterine cervix is one of the most common malignancies in women. Metastatic recurrence of cervical cancer in spleen is rare, mostly seen in autopsies. Splenic metastasis from cervical cancer in a living patient without disseminated metastases is rarer. Here, we present the case of a lady aged 46 years with cervical cancer-squamous cell carcinoma-who had undergone radical hysterectomy and postoperative 50 Gy of intensity modulated radiation therapy in 25 fractions and 50 mg of weekly cisplatin for 6 weeks. She was doing well for 17 months. Then, she developed fever and anorexia, and was detected to have splenic lesion and a lesion in the pelvic mesentery in PET/CT (positron emission tomography-computed tomography). Laparoscopy showed enlarged spleen with a mass lesion and a mass in ileal mesentery adherent to the peritoneum over the fundus of bladder and greater omentum. She underwent resection of a segment of ileum with the mesenteric lesion and omentum and bladder peritoneum laparoscopically and splenectomy. Histopathological examination revealed both the mesenteric and splenic lesions to be metastases from poorly differentiated carcinoma, which was from the cervical cancer. Immunohistochemistry was suggestive of squamous cell carcinoma associated with high-risk human papilloma virus. After the postoperative recovery, patient was started on ciplatin with paclitaxel chemotherapy.

Castleman's Disease Presenting as Peri - Pancreatic Neoplasm.

Castleman's disease (CD) is a relatively singular disorder. Usually presenting as a mediastinal mass, peri pancreatic localization of CD is even rarer. Diagnosis is seldom established pre-operatively. We report two such cases of CD in which peri pancreatic region was involved and were diagnosed on biopsy, hence avoiding complex and high risk surgery.
