Brief Summary:
The study is being done to research if hydroxychloroquine can prevent chemotherapy induced peripheral neuropathy. Certain chemotherapy drugs, like paclitaxel, are known to cause neuropathy which can impact quality of life. Currently, there are no options for preventing peripheral neuropathy. In addition, there are no useful methods to assess peripheral nerve damage. This study will also explore using a study MRI of patients' feet prior to starting chemotherapy and after they have completed chemotherapy to see if there is any difference in their nerve structure.

Arm Intervention/treatment
Experimental: Addition of Hydroxychloroquine to paclitaxel
Hydroxychloroquine will be added to chemotherapy in patients with early stage (1-3) breast cancer and gynecological cancers.
Drug: Hydroxychloroquine
Hydroxychloroquine will be administered at 600 mg po BID for 3 days prior to starting chemotherapy, continued during the course of chemotherapy, and for 7 days after chemotherapy.

Primary Outcome Measures :
  1. Symptomatic CIPN [ Time Frame: Throughout study completion, an average of 6 months ]
    The primary endpoint is symptomatic CIPN defined as increase in in FACT-GOG/Ntx-12 questionnaire score of greater than or equal to 3 points post-chemotherapy with hydroxychloroquine in combination with paclitaxel chemotherapy in patients with early-stage breast cancer or gynecologic malignancies.

Secondary Outcome Measures :
  1. Predicting Symptomatic CIPN: FA and ADC values derived from DTI [ Time Frame: Baseline ]
    Baseline fractional anisotrophy (FA) and apparent diffusion coefficient (ADC) values derived from DTI will be used to predict symptomatic CIPN prior to starting and end of chemotherapy.

  2. Predicting Symptomatic CIPN: change in FA and ADC [ Time Frame: Baseline and 12 weeks ]
    Change in mean FA and ADC prior to starting and end of chemotherapy will be calculated. The mean of the change in FA and ADC values with 95% confidence intervals will be estimated (post- minus pre- chemotherapy). The baseline values and the change of FA and ADC will be used to predict the development of symptomatic CIPN using logistic regression.

  3. Predicting Symptomatic CIPN: baseline NF-L levels [ Time Frame: Baseline ]
    Baseline level of neurofilament light chain (NF-L) will be used to predict symptomatic CIPN. The baseline values will be used to predict development of symptomatic CIPN using logistic regression.

  4. Predicting Symptomatic CIPN: Changes in NF-L levels [ Time Frame: Baseline and 12 weeks ]
    Changes in NF-L levels with chemotherapy used to predict development of symptomatic CIPN. NF-L measures will be summarized across time and analyzed using linear mixed effects model.
