Psychometric analysis of Marathi version of an updated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC QLQ-H&N43).

BACKGROUND: The aim of this study was to perform a psychometric analysis of the Marathi version of an updated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC QLQ-H&N43) in patients of head and neck squamous cell carcinoma (HNSCC). MATERIAL AND METHODS: After an institutional ethics committee approval and linguistic validation, the Marathi version of EORTC QLQ-H&N43 was served to consecutive eligible, Marathi-speaking HNSCC patients of oral cavity, oropharynx, hypopharynx and larynx, registered from August 2019 to March 2021 and who consented to the study. Performance status scale was used for perceptive assessment of organ function. Psychometric analysis was performed using SYSTAT v. 12 (Cranes software, Bengaluru). RESULTS: A total of 129 patients participated in the study with a median age of 67 years and the man-to-woman ratio of 100:29. The commonest sub-site reported was the oral cavity (61.24%) and the majority were in stage IV disease (69.76%). Ninety patients completed the questionnaire before being started on active oncology treatment at our center. 39 patients completed the questionnaire at pre-treatment and first follow-up. The questionnaire was filled on their own (module) by 32.55% of patients while 67.44% of patients required some kind of assistance (schedule). Internal consistency was moderate to high. The criterion and construct validities were acceptable. The questionnaire was sensitive to change with stage and time. No significant difference was observed in module versus schedule subgroup except for 2 out of 19 item-scales. CONCLUSION: Marathi translation of EORTC QLQ-H&N43 is a sensitive, reliable and valid tool when applied to patients of HNSCC. It can be considered as a schedule.

Marathi translation, linguistic validation, and cross-cultural adaptation of M.D. Anderson dysphagia inventory in patients of head and neck squamous cell cancer.

Background: Self-reported treatment outcome is a better way to measure patient's quality of life (QOL). This study was undertaken to translate dysphagia-specific QOL questionnaire M. D. Anderson Dysphagia Inventory (MDADI) in Marathi language, its linguistic validation, and cross-cultural adaptation in patients of head and neck squamous cell cancer (HNSCC). Methods: After Institutional ethics committee approval, MDADI was translated into Marathi with prior permission from the author of original English questionnaire (AOEQ). The translation procedure included - two forward translations (English to Marathi), formation of first intermediate Marathi translation (FIMT), two back translations (BT) (Marathi to English) of FIMT and interim Marathi translation (IMT) formation. Second intermediate Marathi translation (SIMT) was prepared after face validation of IMT by Marathi subject expert. Pretesting of SIMT was done in 10 patients of HNSCC for linguistic validation and cross-cultural adaptation. After incorporating the patients' suggestions, final Marathi translation was formulated and forwarded to primary author for approval. Results: The grammatically acceptable and conceptually equivalent face-validated SIMT was prepared and given to HNSCC patients. The questionnaire was well understood and unobjectionable reflecting its linguistic validity and cross-cultural adaptation. Some of the patients suggested changes in a few words which were then rectified, rechecked with BT, and the final Marathi translated questionnaire was prepared. The credit statement for AOEQ was used as a footnote in the translated questionnaire. Conclusion: Marathi translation of MDADI is well accepted and comprehensible. It can be used for future studies.

Pretreatment hematological parameters as predictors of tumor granulocyte-colony-stimulating factor expression in patients of head-and-neck squamous cell carcinoma.

Background: Tumor secreting granulocyte-colony-stimulating factor (G-CSF) and/or G-CSF therapy has been documented as a poor prognostic factor. Tumor G-CSF study is a relatively costly and sparsely available investigation. Therefore, this study was undertaken to predict tumor G-CSF score from pretreatment hematological parameters (PTHP) in patients of head-and-neck squamous cell carcinoma (HNSCC). Materials and Methods: This pilot study was performed after institutional ethics committee approval. Consecutive nonmetastatic HNSCC patients of oral cavity, oropharynx, hypopharynx, and larynx registered from February to December 2019 were analyzed. Patients whose PTHP and formalin-fixed-paraffin-embedded tissue were available, were included. PTHP (absolute neutrophil count [ANC], absolute monocyte count [AMC], absolute lymphocyte count [ALC], neutrophil-to-lymphocyte ratio [NLR], and platelet-to-lymphocyte ratio [PLR]) done before any active oncology treatment, were noted. A semiquantitative tumor G-CSF score was calculated. Tumor G-CSF score and PTHP were correlated with clinicopathological factors. Statistical analysis was performed using SYSTAT version 12. Results: Data of 47 eligible patients were analyzed. The median age at presentation was 60 years. The male-to-female ratio was 43:4. The most common head-and-neck subsite was oropharynx (31.92%), and majority of patients presented with Stage IVA disease (51.1%). Higher tumor G-CSF score was significantly associated with a higher T-stage (P = 0.013). Tumor G-CSF score was directly proportional to ANC, AMC, and ALC while it was inversely proportional to NLR and PLR. Regression equations to predict the tumor G-CSF score when PTHP are known, were determined. Conclusions: PTHP can predict the tumor G-CSF score which may guide G-CSF-directed therapy. Future studies with large number of patients are needed to elucidate its clinical use.

Subjective and perceptive assessment of speech/voice and swallowing function before and after radiation therapy in patients of head-and-neck squamous cell cancer.

Aim: To prospectively assess subjective and perceptive speech/voice and swallowing function before and after radiation therapy (RT) in patients of head-and-neck squamous cell cancer (HNSCC). Materials and Methods: The study cohort comprised eligible consecutive HNSCC patients planned for curative RT from April 2018 to July 2018 who consented for the study. Prospective evaluation of speech/voice and swallowing function was done before and after RT. For subjective and perceptive evaluation of speech/voice, speech handicap index (SHI) and Grade, Roughness, Asthenia, Breathiness, and Strain (GRABS) Scale was used, respectively. For subjective and perceptive evaluation of swallowing, M D Anderson Dysphagia Inventory (MDADI) and Performance Status Scale for head and neck (PSSHN) were used, respectively. All patients were taught speech/voice and swallowing exercises before RT. Statistical analysis was performed using SYSTAT version-12 (Cranes software, Bengaluru). Results: The study cohort comprised 30 patients of HNSCC with a median age of 57 years and male-to-female ratio of 4:1. The most common subsite was the oral cavity (43.33%) and a majority (76.66%) presented in the locally advanced stage. Post-RT there was significant improvement in speech/voice function (SHI P = 0.0006, GRABS score P = 0.003). Perceptive assessment of swallowing function by PSSHN showed significant improvement (P = 0.0032), but subjective assessment by MDADI showed no significant (P = 0.394) improvement until the first follow-up. Conclusion: Speech/voice function improved significantly after radiotherapy when combined with rehabilitation exercises. Swallowing function did not improve till the first follow-up. Future studies with the large number of patients and long-term follow-up are needed to document the changes in organ function.

Serum 25-hydroxy vitamin-D levels in head and neck cancer chemoradiation therapy: Potential in cancer therapeutics.

Background: To evaluate the relation between serum-25-hydroxy Vitamin-D levels (S25OHVDL) and concurrent chemoradiation therapy (CTRT) toxicities in patients of head and neck squamous cell cancer (HNSCC). Methods: After an institutional ethics committee approval, consecutive HNSCC patients who received radical/adjuvant CTRT were prospectively evaluated. Patients were assessed for CTRT toxicities using Common Terminology Criteria for Adverse Events version 5.0 (CTCAE-v5.0) and the response was evaluated according to Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST-1.1). S25OHVDL was assessed at the time of the first follow-up. Patients were divided into group A (Optimal) and group B (suboptimal) according to S25OHVDL. The treatment toxicities were correlated with S25OHVDL. Results: Twenty-eight patients were evaluated for the study. S25OHVDL was optimal in eight (28.57%) and suboptimal in 20 patients (71.42%). Mucositis and radiation dermatitis were significantly more in subgroup B (P-value 0.0011 and 0.0505, respectively). Relatively lower but nonsignificant hemoglobin and peripheral white blood cell counts were observed in subgroup B. Conclusion: Suboptimal S25OHVDL was associated with significantly more skin and mucosal toxicities in HNSCC patients treated with CTRT.

Multiple primary head and neck squamous cell cancer: Lessons learnt.

AIM: To analyze the demographic profile, treatment outcome, and factors affecting them in multiple primary head and neck squamous cell cancer (MPHNSCC) patients. MATERIALS AND METHODS: Hospital case records of patients with histopathology proven MPHNSCC registered in the radiation oncology department from January 2008 to December 2020 were retrospectively studied. Modified Warren-Gates criteria were used to define MPHNSCC. Demographic and clinical details were recorded and analyzed. RESULTS: Twenty-seven patients had histopathology proven MPHNSCC. The median age at diagnosis of an index case was 50 years (minimum 26, maximum 70) with a male to female sex ratio of 22:5. Seventeen (62.96%) patients were tobacco users; either smoked or smokeless. The oral cavity was the commonest sub-site for both an index and second primary malignancy (22 patients; 81.48%) and the majority presented in a locally advanced stage of disease (10; 37.03% and 16; 62.95% for an index and second primary, respectively). The presentation was simultaneous, synchronous, and metachronous in 1 (3.7%), 2 (7.4%), and 24 (88.89%) patients, respectively. Two patients had three sites of MPHNSCC. The average duration of chronicity was 54.37 months (min. 8 and max. 156). MPHNSCC were ipsilateral in 10 (37.04%) patients and re-irradiation was planned for 22 (81.48%) patients with 50% treatment compliance. At the time of the last hospital visit, 18 (66.66%) patients were alive with disease, 7 (25.92%) patients were alive without disease, and 2 (7.40%) patients died of disease. CONCLUSION: A higher percentage of MPHNSCC originated from the oral cavity and the majority presented in the locally advanced stage of disease; despite the site being accessible to self-oral examination. Patient education and physician's awareness regarding the MPHNSCC are needed.

Multiple malignant primary tumors (non-head and neck): Contemplation needed.

BACKGROUND: The incidence of multiple malignant primary tumors (MMPT) is increasing which needs attention. Hence, we undertook this study to analyze clinico-demographic details and treatment outcomes in patients with non-head and neck MMPT. MATERIALS AND METHODS: Hospital case records of patients with histopathology proven MMPT registered in the radiation oncology department from January 1, 2008 to December 31, 2020 were retrospectively studied. Modified Warren-Gates criteria were used to define MMPT. Patients with MMPT of the head and neck (both an index and second primary as head-neck) were excluded from the study. Demographic and clinical details were recorded and analyzed. RESULTS: Forty-two eligible cases of non-head and neck MMPT were studied. The median age at diagnosis of an index case was 55 years (minimum 21, maximum 85) with a male to a female sex ratio of 5:37. Twelve patients had synchronous (28.57%) and 30 had metachronous (71.42%) MMPT. The average period between metachronous tumors was 77.77 months (minimum 12, maximum 312). The most common site of an index and second primary tumor was the breast (26; 61.90% and 23; 54.76%, respectively). Seventeen (65.38%) out of 26 index breast cancer were bilateral breast cancer and nine were others. In six cases of MMPT, there was an association between the breast and cervix. CONCLUSION: Breast cancer was the most common site for both an index and second primary malignancy followed by genital cancers. With cautious monitoring and patient education, second primary tumor could be detected earlier and managed better giving a good quality of life to patients.

Association between depressive symptoms and socioeconomic status in head and neck cancer patients attending rural tertiary health care center.

AIM: To study the association between depressive symptoms and socio-economic status (SES) in patients with head and neck cancer (HNC). MATERIALS AND METHODS: Histopathology-proven non-metastatic and non-recurrent HNC patients attending radiation oncology services in February and June 2021 who consented to the study were evaluated with an interview. Hamilton Depression Rating Scale (HDRS) and modified BG Prasad classification were used to assess depressive symptoms and SES, respectively. Statistical analysis was done using SYSTAT version 12 (by Crane's software, Bangalore). RESULTS: The study cohort comprised 100 patients. The median age was 55 years (minimum: 28, maximum: 86) with a male-to-female ratio of 2.57:1. The majority of patients were educated beyond middle-school level (44%), of middle SES (47%), oral cavity subsite (68%), stage IVA (36%) disease, and were on treatment (79%). HDRS scores showed absent, moderate, and severe depressive symptoms in 21, 63, and 16 patients, respectively, that is, the prevalence of depressive symptoms was 79%. Lower socioeconomic strata showed a significantly higher prevalence of severe depressive symptoms (P-value = 0.01). HDRS score was significantly higher in females (P-value = 0.024) and in patients who were illiterate or were educated less than middle-school level (P-value = 0.010). No statistically significant difference was found between HDRS score and age of patient, stage and site of disease, and on treatment or follow-up status. CONCLUSION: Depressive symptoms are common in patients with head and neck cancer. Low socioeconomic status (SES), female gender, and education less than middle school are associated with severe depressive symptoms. Psycho-oncological and psychotherapeutic interventions are the need of the hour.

Oncology treatment outcome in human immunodeficiency virus-positive cancer cervix patients: Where we are and what we achieved?

Objective: To find out the epidemiological factors and oncology treatment outcome in human immunodeficiency virus-positive cancer cervix patients (HPCCP). Materials and Methods: After institutional ethics committee approval, hospital case records of HPCCP registered at the radiation oncology department from January 2011 to December 2018 were retrospectively studied. Results: The case records of 22 eligible HPCCP were studied. Median age at presentation was 42.5 years. 90.90% of the patients were below 55 years of age. The duration of symptom was <3 months in 63.64% of patients. 68.18% of the patients were FIGO Stage III. Only 11 patients completed the planned treatment. Total target equivalent dose of 2 Gy per fraction delivered was 66 Gy. Seven patients had complete response. Four patients had local recurrence. Median disease-free and overall survival was 27 (14-38) and 18 months (2-48), respectively. Conclusion: HPCCP present at relatively early age and advanced stage despite short symptom duration. Poor patient compliance and treatment alteration have led to suboptimal outcome.

Concurrent chemotherapy with high-dose rate brachytherapy after treatment with chemoradiotherapy in cases of locally advanced carcinoma cervix: A study from rural area of Maharashtra, India.

Aim: This study aims to evaluate the efficacy, feasibility, tolerability, and toxicity of concurrent chemotherapy and brachytherapy for locally advanced cervical carcinoma. Materials and Methods: Forty patients of cervical carcinoma were included in this study. The study period ranges from October 2016 to September 2019. Patients were evaluated and treated as per the protocol: external beam radiotherapy (50 Gy in 25 fractions) and concurrent weekly chemotherapy with injection (Inj.) cisplatin (30 mg/m2) followed by high-dose rate brachytherapy (3 fractions of 7 Gy each) and concurrent chemotherapy Inj. cisplatin (30 mg/m2). Results: Out of 40 patients enrolled in the study, 36 patients completed the treatment (17 Stage II and 19 Stage III). The incidence of Grade I and II skin toxicities were 78% and 10%, respectively. The incidence of genitourinary toxicities with respect to Grade I and II were 72% and 12%, respectively. There were Grade III hematological toxicities in two patients and the brachytherapy treatment was delayed for 4-6 days. The overall complete response was found in 28 (78%) patients, partial response in six (16.7%) patients, and progressive disease in two (5.6%) patients at 3 months of follow-up. On the last follow-up, 21 (58%) patients were disease-free and there was disease failure in seven patients (5 local recurrence and 2 with distant metastasis). Conclusion: Brachytherapy with the addition of concurrent chemotherapy is effective and feasible with acceptable toxicity for advanced stages of carcinoma cervix. This study upholds an interesting approach that can be regarded as feasible and tolerable for cervical cancer patients.

Evaluation of chronic toxicological profile of herbo-mineral formulations: Shwaskas Chintamani Rasa and its marketed formulation namely Kas Shwas Hari Rasa.

BACKGROUND: Shwaskas Chintamani Rasa (SKC) and Kas Shwas Hari Rasa (KSH) are the Ayurvedic herbo-mineral formulations. These Ayurvedic formulations contain heavy metals which is the reason of concern and might bring up the safety issue. OBJECTIVE: This research article is aimed to study chronic toxicity of SKC and KSH for safety aspect in Wistar rats. MATERIAL AND METHOD: A study group of 220 healthy rats were divided into six groups. These rats were administered with SKC and KSH formulations where both the formulations were administered for 180 consecutive days. SKC was administered at doses of 58 mg/kg (equivalent to therapeutic dose i.e. TD), 145 mg/kg (2.5 TD), 290 mg/kg (5 TD) and KSH was administered at dose of 58 mg/kg (TD). According to OECD guideline 452, the effect of these formulations was examined on hematology, serum biochemistry and histopathology of various organs. RESULTS: Both the formulations did not produce any signs or symptoms of treatment related toxicity in both male and female Wistar rats at therapeutic dose (TD), 2.5 times TD and 5 times TD. CONCLUSION: Based on these findings, the NOAEL (No observed adverse effect level) for test formulations SKC and KSH tablets in male and female wistar rats concluded to be preclinically safe.

Marathi translation, linguistic validation, and cross-cultural adaptation of speech handicap index and voice handicap index in patients of head and neck squamous cell cancer.

Background: Patient reported treatment outcomes is a better way to measure the quality of life (QOL). This study was undertaken to translate the speech handicap index (SHI) and voice handicap index (VHI) in Marathi language and its linguistic validation and cross-cultural adaptation in patients of head and neck squamous cell cancer (HNSCC). Methods: SHI and VHI were translated into Marathi with prior permission from the respective authors of original English questionnaire (RAs). The translation procedure for each tool included two forward translations (English to Marathi), the formation of first intermediate Marathi translation (FIT), two back translations (Marathi to English) of FIT, and interim Marathi translation (IT) formation. The second intermediate Marathi translation (SIT) was prepared after face validation of IT by a subject expert. Pretesting of SIT was done in 20 patients of HNSCC to validate linguistic and cross-cultural adaptation. By incorporating the patient's suggestions, the final Marathi translation was prepared and sent to primary authors for approval. Results: The grammatically and conceptually acceptable and face validated SIT was prepared and administered to HNSCC patients. The patients of the oral cavity and larynx were in SHI and VHI group, respectively (ten patients in each group). The questionnaire was well understood reflecting its linguistic and cross-cultural adaptation. Some of the patients suggested changes in a few words which were then corrected, rechecked with back translation, and final Marathi translated questionnaire was prepared. It was approved by RAs. Conclusion: Marathi translation of SHI and VHI are well accepted and comprehensible. It can be used for future studies.

Assessment of Chronic Toxicity of an Ayurvedic Herbo-Metallic Formulation Rasaraj Rasa in Wistar Rats.

Objectives: This study aimed to assess the adverse effects of Rasaraj Rasa tablets after repeated oral administration for 180 days in Wistar rats. Methods: Wistar rats were divided into five groups, of which three were treated with 54, 162, and 270 mg/kg body weight of Rasaraj Rasa, respectively, which correspond to one, three, and five times the proposed human therapeutic dose, for 180 days consecutively. The fifth group (satellite) also received 270 mg/kg body weight of Rasaraj Rasa for 180 days. Body weight and food intake were measured weekly. At the end of the study, all rats were sacrificed, and their blood, serum, and organs were collected and examined using hematology, serum biochemistry, gross pathology, and histopathology tests. In contrast, the satellite group was kept for 4 weeks after treatment. Results: No significant treatment-related toxicological findings were observed in the clinical features, body weight, laboratory findings, and pathological findings of the high-dose treated groups, when compared to those of the control group. Conclusion: The no-observed-adverse-effect-level for Rasaraj Rasa in Wistar rats is set at 270 mg/kg body weight.

Various addiction patterns, dietary habits, associated medical problems, and socioeconomic status in gastrointestinal malignancies: A prospective study in rural area of Maharashtra, India.

BACKGROUND: Gastrointestinal (GI) malignancies are increasing with advancing age. Various addictions and poor dietary habits are among the major risk factors. Early detection is difficult until patient notices symptoms. Primary prevention by knowing various risk factors and early symptom awareness will help in early diagnosis and better treatment outcome. OBJECTIVES: This study is carried out to see various addiction patterns, dietary habits, associated medical problems, and socioeconomic status with various sites involved in GI malignancies, at a tertiary care teaching hospital of Western Maharashtra, India. MATERIALS AND METHODS: Prospective questionnaire-based study was carried out for 11 months. A total of 100 diagnosed carcinoma cases of GI tract malignancy were taken for study. RESULTS AND CONCLUSIONS: Out of total 100 cases, 61 were male and 39 were female. The most common site involved was esophagus (41) followed by rectosigmoid, colon and cecum, stomach, and anal canal (29, 14, 13, and 3, respectively). There were 45% of cases above 60 years of age. The most common addiction was smokeless tobacco. Most of the patients belonged to lower and upper lower class (64%). Majority of cases (81%) were nonvegetarian, only 16% were pure vegetarian. Most of the cases (85%) were in advanced stage of disease (III and IV). Awareness program for harmful effects of various addictions and importance of high-fiber diet (vegetarian diet) will help in health promotion and prevention of various malignancies. Awareness about the early symptoms of GI malignancy will help in early detection of disease and better treatment outcome.

Radiation burn--from mechanism to management.

Radiation burn can occur with diagnostic or therapeutic use of ionizing radiation. A nonintentional radiation burn is relatively uncommon. Skin has a specific tolerance to radiation, above which different grades of radiation burn can occur. Being a rare and less studied problem, no precise guideline is present for its management. Because of few unresolved issues in the pathophysiology of deep radiation burn, its management is difficult. To date no specific guidelines are present for the treatment of radiation burn.

Quality of voice after radiotherapy in early vocal cord cancer.

Early glottic cancer (T1, T2N0M0), a disease of the voice box, mainly affects the voice. It can be effectively treated with both surgery and radiotherapy. Preservation of the voice while treating vocal cord cancer is not simply retaining the ability to vocalize. It is the determinant of choice of treatment and quality of life following curative management. Radiotherapy has resulted in excellent control rates with voice preservation and has been the standard of care for many decades. Several patient- (e.g., smoking, age, amount of talking during treatment), disease- (e.g., extent and site of lesion) and treatment- (e.g., radiation field size and dose, voice therapy) related factors adversely affect the quality of voice after radiotherapy. Several studies have evaluated voice quality either subjectively or objectively. Still, little is known about it. Voice quality after radiotherapy improves but does not reach the standard of the normal controls.

Factors affecting the quality of voice in the early glottic cancer treated with radiotherapy.

AIMS: To prospectively analyze the objective voice quality before and after radiotherapy (RT) for early glottic cancer and to evaluate the role of different factors that may affect it. METHODS: Patients with T1-T2N0M0 glottic cancer underwent voice quality assessment before treatment and after radical RT. Post-RT voice quality was compared to the voice at diagnosis and the voice of healthy individuals used as controls. A comprehensive set of voice parameters were measured. The effects of age, smoking history, T stage, anterior commissure (AC) involvement, radiation dose, fractionation and volumes on pre-treatment and post-treatment voice quality were analyzed. RESULTS: The voice quality data of 50 patients were analyzed. Following treatment, there was a significant improvement in the majority of measured parameters. However, perturbation and HNR remained inferior compared to controls. A history of smoking, AC involvement and larger RT volumes resulted in poorer voice parameters following RT. There was no significant impact of age alone. T2 tumors had an inferior voice quality before treatment, but did not remain inferior following RT. Hypofractionated RT did not show any negative impact. CONCLUSIONS: There is a considerable improvement of voice quality following RT. Several factors may have specific effects on pre-treatment and post-treatment voice.
