Registry Trial to Evaluate the Safety and Efficacy of Hyperthermia in Locally Advanced Cancers

Mahatma Gandhi Institute of Medical Sciences500 enrolled

Overview

Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sevagram, District Wardha, Maharashtra, India is located in a rural setup and caters to a very underprivileged patient population with limited resources to even pay for their treatment. As per the latest Indian Cancer Registry Report 2020, of the 28 population based cancer registries (PBCR), the age adjusted incidence rates (AAR) in males and females are 64.9 and 69.9. This makes the AAR in Wardha District (district where MGIMS is located) as one of the lowest ranked AAR both for male (national range: 39.5 - 269.4) and females (national range: 49.4 - 219.8) in the country. However, the %mortality / incidence, is one of the highest for Wardha, both for males (65.9%, national range: 14.7% - 71.9%) and females (53%, national range: 9% - 63%). This indicates that the prognosis of patients in this district is one of the worst in India and thus requires a new approach to their standard therapeutic option. This has to be cost-effective, without any significant additional morbidity, and should used in conjunction to the standard treatment of radiotherapy and/or chemotherapy. Hyperthermia, which is raising the tumor temperature to 40 - 43°C is perhaps one of the oldest forms of treatment for cancer. Hyperthermia, being a potent radiosensitizer, a chemosensitizer, an immunomodulator with no significantly added side effects, could be an effective therapeutic modality that could be expected to improve the outcome in these patients. However, it also needs to be cost-effective and require low capital cost investment so that other centers, especially in low and low-middle income countries could also introduce hyperthermia to the therapeutic armamentarium for cancer. This is a registry trial for patients being treated with hyperthermia along with radiotherapy and/or chemotherapy as per the standard departmental protocol for various locally advanced cancers.

To carry out a registry trial to evaluate the safety and efficacy of hyperthermia delivered by a repurposed short wave diathermy unit working at 27.1 MHz along with radiotherapy and/or chemotherapy in patients with locally advanced tumours of head neck cancers, cancer cervix, breast, oesophagus and anorectum attending the department of radiotherapy, MGIMS. This would help to create an organized system that uses observational methods to collect uniform data on safety and efficacy of hyperthermia when used in conjunction with standard therapeutic modalities of radiotherapy and/or chemotherapy. The study would help to, i. Evaluate the specific outcomes with hyperthermia in terms of the following clinical endpoints with hyperthermia 1. Locoregional tumour control 2. Local disease free survival 3. Overall survival ii. Evaluate the safety of hyperthermia along with standard therapeutic modalities of radiotherapy and/or chemotherapy 1. Acute morbidity 2. Late morbidity iii. Evaluate the feasibility of carrying out hyperthermia by repurposing 27.12 MHz short wave diathermy unit that could be cost-effective

Adequate kidney and liver functions as assessed on biochemical investigations 7. Absence of psychological, familial, sociological or geographical condition that could potentially hamper compliance with the study protocol and follow-up schedule Exclusion Criteria: 1. Prior radiotherapy to the site of treatment 2. No prior or concurrent malignancies other than surgically treated squamous cell or basal cell carcinoma of the skin which are not in the area of the present malignancy 3. Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator would preclude the patient from meeting the study requirements. 4. Patients having metal implants, pacemakers or clustered markers. 5. Connective disease disorders that contraindicate radiotherapy, e.g., Scleroderma 6. Any known contraindication or hypersensitivity to the chemotherapeutic agents 7. Pregnancy, lactation period or lack of reliable contraception 8. Any other disease or therapy, which, according to the investigator, present a risk to the patient or which are not compatible with the aims of the clinical trial 9. Indications that the person concerned will possibly not keep to the clinical trial plan because of unwillingness to cooperate or difficulties in keeping the check-up appointments 10.
