Centchroman as First-line Treatment for Mastalgia: Results of an Open-label, Single-arm Trial

The effect of centchroman on mastalgia: a systematic review

OBJECTIVES

We carried out a systematic review of the literature to evaluate the effect of centchroman on mastalgia as well as any side effects.

METHODS

The databases of the Cochrane Library, Medline (PubMed), Embase, ProQuest and ClinicalTrials.gov were systematically searched. The quality of randomised controlled clinical trials (RCTs) was assessed using the Cochrane Collaboration's tool for assessing risk of bias in randomised clinical trials. The quality of non-randomised clinical trials was assessed using the Cochrane risk of bias assessment tool for non-randomised studies of interventions (ROBINS-I). Owing to different outcomes reporting, a meta-analysis of the results was not possible.

RESULTS

Thirteen papers were included in the study. Of these, 12 showed a significant effect of centchroman in reducing breast pain at 3 months. One study that compared the effect of centchroman with that of tamoxifen reported a significant reduction in breast pain in both groups at 3 months; the difference between the two groups was not significant. Six studies showed the effectiveness of centchroman at 6 months. None of the papers reported any serious side effects of centchroman.

CONCLUSIONS

Since a meta-analysis could not be conducted and the quality of the papers was low, there was insufficient evidence to evaluate the effect of centchroman on mastalgia. It is therefore recommended to conduct well-designed RCTs to compare the effect of centchroman on mastalgia with that of a placebo or other medication.

Cyclic and non-cyclic breast-pain: A systematic review on pain reduction, side effects, and quality of life for various treatments

CYCLIC AND NON-CYCLIC BREAST-PAIN

A systematic review on pain reduction, side effects, and quality of life for various treatments.

BACKGROUND

No clear systematic-review on all the various treatment regimen for (Non-) cyclical-breast-pain currently exists.

OBJECTIVES

The aim of this study was to assess the various forms of therapy for treatment of breast-pain and the evidence for their effectiveness.

SEARCH STRATEGY

Search-terms included 'mastalgia' and 'therapy' or 'hormones' or 'nsaid' or 'psychotherapy' or 'analgesia' or 'surgery', and synonyms.

SELECTION CRITERIA

The review was conducted according to the Preferred Reporting Items for Systematic-reviews and Meta-Analysis guidelines. RCT's and pro-/retrospective studies reporting on treatment of breast-pain were considered eligible. Minimal follow-up and sample-size criteria were 6 months and 10 patients respectively.

DATA COLLECTION AND ANALYSIS

Data was extracted using standardized tables and encompassed number of subjects, type of breast-pain and treatment, efficacy of treatment and clinical complications/side-effects. No pooling of data could be achieved due to heterogeneity amongst studies.

MAIN RESULTS

Twenty-three studies were included, that reported on 2100 patients in total. Topical-Diclofenac was found to reduce pain by 58.7 and 63.3 on a Visual-Analogue-Scale (VAS) in cyclical and non-cyclical-breast-pain respectively. Persistent cyclical-breast-pain can be treated with short courses (2-6 months) of either Bromocryptine (VAS↓=25.4) or Danazol (VAS↓=33.6) as long as benefits outweigh the side-effects. Last-resort options for unresponsive and severe debilitating breast-pain include surgery in the form of bilateral mastectomy with reconstruction.

CONCLUSIONS

Pain reduction in patients with breast-pain can be achieved with analgesics, hormonal-regimen and possibly surgery as a last resort. Additional studies are needed with well-described patient-characteristics, robust study set-up, and longer follow-up times.

Effectiveness of Centchroman on Regression of Fibroadenosis and Mastalgia

INTRODUCTION

Fibroadenosis and mastalgia are common among the women in reproductive age group. Treatment for these conditions is not yet standardised. Most of the drugs used for fibroadenosis and mastalgia are expensive and have side effects.

AIM

To find out the efficacy of centchroman, a Selective Estrogens Receptor Modulator (SERM) on regression of fibroadenosis and mastalgia.

MATERIALS AND METHODS

Fifty one patients with mastalgia/fibroadenosis were treated with centchroman 30mg once daily on alternate days for a period of 3 months and followed up weekly for six months with Mastalgia chart and Visual Analog Scale (VAS) pain score.

RESULTS

Before starting treatment, four patients presented with pain score of 6 followed by, 37 patients with a score of 4 and 10 patients with a score of 2. All the patients were started on tab centchroman 30mg OD alternate days and were reviewed on weekly basis with Mastalgia chart and VAS pain score for three months. On fifth and sixth visit, 46 patients reported with pain score 0, one with pain score of 2 and four with pain score of 6. The efficacy of centchroman was found to be significant (p-value = 0.001). Three patients (5.9%) reported epigastric pain and ten patients (19.6%) reported menstrual delay. A total of 38 patients did not complain of any side effect.

CONCLUSION

Our study proves that centchroman is a safe and cost effective drug with significant efficacy on regression of fibroadenosis and mastalgia with minimal side effect.
