Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if vitamin B prophylaxis is effective in attenuating chemotherapy-induced peripheral neuropathy in adult ovarian cancer patients. The main questions (primary outcomes) it aims to answer are:

* The severity of chemotherapy-induced peripheral neuropathy in ovarian cancer patients undergoing a weekly paclitaxel-based regimen in the vitamin B prophylactic group versus non-prophylactic group.
* Severity of chemotherapy-induced peripheral neuropathy in diabetic patients versus non-diabetic patients in both prophylactic and non-prophylactic groups.

Participants will:

Take drug oral vitamin B complex every day as prophylaxis for 6 months. Visit the clinic once every week for their weekly Paclitaxel regimen, checkups and tests.

Keep a diary of their symptoms.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients received oral vitamin B complex as prophylaxis prior to starting their paclitaxel-based regimen and patients in the non-prophylaxis group received oral vitamin B complex upon developing chemotherapy-induced peripheral neuropathy during their treatment with paclitaxel-base regimen. Gabapentin was given to the patients in either groups upon aggravation of CIPN symptoms whether in severity or neuropathic pain according to peripheral neuropathy grading.

Secondary outcomes:

* The number of patients in both prophylactic and non-prophylactic groups who required Gabapentin upon uncontrolled or aggravation in CIPN with vitamin B complex only.
* Impact of vitamin B complex prophylaxis on dose modification of paclitaxel-based regimen.
* Association between dose modification and CA 125 status.
* Progression-free survival (PFS) was evaluated at the end of the study.
