Impact of COVID-19 Pandemic on Patterns of Care and Outcome of Head and Neck Cancer: Real-World Experience From a Tertiary Care Cancer Center in India.

PURPOSE: The COVID-19 pandemic has caused unprecedented health, social, and economic unrest globally, particularly affecting resource-limited low-middle-income countries. The resultant curfew had made the access to and delivery of cancer care services an arduous task. We have reported the patterns of care and 1-year outcome of head and neck squamous cell carcinoma (HNSCC) treatment before and during COVID-19 lockdown at our institution. MATERIALS AND METHODS: Patients who underwent radiation therapy (RT) for nonmetastatic HNSCC between March 1, 2020, and July 31, 2020, were included in the COVID-RT group, and those who were treated between October 1, 2019, and February 29, 2020, were included in the preCOVID-RT group. RESULTS: A total of 25 patients were in the COVID-RT group, and 51 patients were in the preCOVID-RT group. An increase in the incidence of locally advanced cancers across all subsites was observed in the COVID-RT group. There was a steep increase in the median overall RT treatment duration (52 v 44) and median break days during RT (10 v 2) in the COVID-RT group. The median follow-up period of all patients was 18 months. The progression-free survival at 1 year in the COVID-RT group and preCOVID-RT group was 84% and 90%, respectively (P = .08), and overall survival at 1 year was 86% and 96%, respectively (P = .06). CONCLUSION: Our study elucidates the adverse impact of the COVID-19 curfew on cancer care and has demonstrated safe delivery of RT for HNSCC without major acute adverse effects. Despite a significant increase in treatment breaks, early outcome data also suggest that 1-year progression-free survival and overall survival are comparable with that of the pre-COVID-19 times; however, longer follow-up is warranted.

Prognostic significance of metabolic tumour volume and maximum standard uptake value of fluor-18-fluorodeoxyglucose positron emission tomography with computed tomography in nasopharyngeal carcinoma.

AIM OF THE STUDY: To evaluate the prognostic role of markers of fluor-18-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG-PET-CT), such as maximum standard uptake value (SUVmax) and metabolic tumour volume (MTV) measured at primary and nodal disease, and their clinical significance in terms of predicting treatment outcomes and survival. MATERIAL AND METHODS: Between January 2017 and January 2020, 20 case records of nasopharyngeal carcinoma patients who underwent 18F-FDG-PET-CT as part of staging workup before radiotherapy and as a part of response evaluation after radiotherapy were retrospectively reviewed. RESULTS: At a median follow-up of 34.7 months, the 2-year progression-free survival (PFS) was 70% and 2-year overall survival (OS) was 79%. Patients with a lower nodal SUVmax (SUVmax-N) had a better 2-year PFS (91% vs. 46%; p = 0.035) and 2-year OS (95% vs. 58%; p = 0.015). A high SUVmax-N of > 10.58 was a negative predictor of OS (95% confidence interval [CI]: 0.93-1; p = 0.003) as well as PFS (95% CI: 0.64-1; p = 0.017). Also, a high MTV > 25.8 cm3 was a negative predictor of PFS (95% CI: 0.58-0.98; p = 0.048). MTV was an independent predictor of PFS and OS on univariate analysis, whereas it was not significant in the Cox regression multivariate analysis. CONCLUSIONS: High values of MTV and SUVmax-N can be considered as independent prognostic factors of OS and PFS in nasopharyngeal cancer patients treated with concurrent chemoradiation, highlighting the need for more intensified treatment.

A pragmatic diagnostic approach to primary intracranial germ cell tumors and their treatment outcomes.

Background: Primary intracranial germ cell tumors (ICGCT) are often diagnosed with tumor markers and imaging, which may avoid the need for a biopsy. An intracranial germ cell tumor with mild elevation of markers is seldom stratified as a distinct entity. Methods: Fifty-nine patients were stratified into three groups: pure germinoma (PG), secreting germinoma (SG) and non-germinomatous germ cell tumors (NGGCTs). Results: At 5 years, progression-free survival and overall survival of the three groups (PG vs SG vs NGGCT) were 91% versus 81% versus 59%, and 100% versus 82% versus 68%, respectively. There was no statistically significant difference in outcome among histologically and clinically diagnosed germinomas. Conclusion: A criterion for clinical diagnosis when a biopsy is not feasible is elucidated, and comparable outcomes were demonstrated with histologically diagnosed germinomas.

Lay abstract Intracranial germ cell tumors (ICGCTs) are rare brain tumors, which often require markers in blood or cerebrospinal fluid, imaging and a tissue biopsy to establish a diagnosis. However, when tissue sampling is not possible, tumor markers can sometimes be used to diagnose ICGCTs. The authors propose guidelines for a diagnosis and a novel subtype of ICGCT called secreting germinoma, which is also described. Fifty-nine patients were separated into three groups: pure germinoma (PG), secreting germinoma (SG) and non-germinomatous germ cell tumors (NGGCTs). At 5 years, progression-free survival and overall survival of the three groups (PG vs SG vs NGGCT) were 91% versus 81% versus 59%, and 100% versus 82% versus 68%, respectively. There was no significant difference in outcome among tumors diagnosed with markers in blood or cerebrospinal fluid and those diagnosed with a biopsy. The proposed guidelines for diagnosis need to be evaluated in future studies. SGs may not warrant aggressive treatment protocols as used in NGGCT, and their outcome as a distinct group needs to be explored in future studies.

Recurrent Kimura's disease of head and neck treated with intensity-modulated radiotherapy.

Kimura's disease (KD) is a rare, chronic inflammatory disorder of unknown aetiology, which commonly affects men of the Asian race. Here, we present a case capsule of a 39- year-old man with KD of the left cheek, managed initially by surgery alone. He developed local recurrence after 6 months and was treated with steroids and isotretinoin. Eventually, steroids were discontinued due to toxicity and the lesion progressively increased in size. The patient was successfully treated using intensity-modulated radiotherapy with simultaneous integrated boost as a primary modality with minimal adverse effects. The patient has good local control and cosmetic outcome with no radiation-related toxicity at a follow-up period of 28 months.

Pediatric hematological malignancy: Identification of issues involved in the road to diagnosis.

INTRODUCTION: Childhood malignancy, although a rare phenomenon, is still the leading cause of mortality in the pediatric population. Early diagnosis and treatment are imperative for the achievement of optimal prognosis. The study of factors facilitating the delay in diagnosis is thus of utmost importance, to both shorten the diagnostic delay and allow for early therapeutic intervention, facilitating a higher prognosis. OBJECTIVE: To assess the referral pattern and the identification of potential delays in the diagnosis of childhood malignancy in a developing country. METHODOLOGY: The study was conducted in the Pediatric Hematology and Oncology department of Sri Ramachandra University, Chennai, India. The study included randomly selected 70 pediatric patients diagnosed with a hematological malignancy, from July 2012-August 2013. The parents were interviewed using a prepared questionnaire about patient symptomatology, interaction with healthcare providers, final diagnosis, and referral details. Data were statistically analyzed using Statistica® (STATsoft). RESULTS: 70 patients were included in the study (69% boys, 31% girls). The diagnostic delay was primarily due to the delay experienced in the healthcare system, with a mean delay of 26 days (Median: 18; Range: 5-39). Those from a lower socioeconomic background and whom opted for a non-allopathic treatment approach experienced higher diagnostic delays. Diagnostic time was significantly shorter for those who visited a pediatrician versus the patients who visited a general physician or super specialties (P = 0.043). CONCLUSIONS: Diagnostic delay is often associated with an extensive disease presentation, an aggressive therapeutic approach, and has a negative impact on patient prognosis. To lower mortality rate and facilitate a favourable prognosis, diagnosis requires a high degree of clinical suspicion and immediate intervention.
