ABSTRACT
BACKGROUND: Solid pseudopapillary neoplasm (SPN) of the pancreas is a low-grade malignant neoplasm with unpredictable behavior. Factors associated with recurrence were not conclusively identified. The aim of this study is to define the clinicopathological criteria for recurrence risk prediction in SPNs based on the most recent scientific evidence and to present our experience with SPNs. METHODS: A retrospective review of patients with SPNs operated on in our institution from June 2012 to June 2018 was completed. Patient characteristics and clinical outcomes were analyzed. A detailed literature review was performed to evaluate the factors associated with the recurrence of SPNs. RESULTS: The cohort consisted of 13 female patients with a median age of 24 years and a mean tumor size of 7.7 cm. Body and tail (53.8%) were the most common location, and distal pancreatectomy with splenectomy was the prevalent surgical procedure. One patient of SPN operated on for local recurrence after 11 years which had high-grade malignant histological features on the previously resected tumor. At a median follow-up of 42 months (range 36 to 108), all patients were disease free and alive. The proposed criteria for predicting recurrence in SPNs include tumor size >8 cm, synchronous metastasis, malignant SPN (according to 2000 or 2010 World Health Organization [WHO] criteria), lymphovascular invasion, pancreatic parenchymal invasion, and high Ki-67 index (>4%). All these are worse prognostic factors and should be considered as high-risk factors for postoperative relapse. CONCLUSION: The above-mentioned criteria can better predict SPN recurrence. Patients with high-risk features should undergo an extended follow-up.
ABSTRACT
Mastalgia is a distressing symptom and may be severe enough to interfere with usual daily activities. Breast pain is either cyclical or noncyclical. Currently; multiple options are available for the treatment of mastalgia including hormonal and nonhormonal agents. This study was conducted to evaluate the role of centchroman as a nonhormonal first-line treatment for moderate to severe mastalgia. To accomplish this; a prospective open-label, single-arm study was done using the Pretest-Posttest Design. A total of 100 women suffering from mastalgia were grouped according to the characteristic pattern of breast pain (cyclic and noncyclic) and received centchroman 30 mg/day for 12 weeks followed by observation for 12 weeks. The efficacy analysis of centchroman was done by comparing median Visual Analog Scale score, median pain duration and side effects over time among the two groups. Centchroman significantly alleviates mastalgia with minimal side effects. The median pain score was significantly reduced over successive visits (1, 4, 12, and 24 weeks). The median pain duration decreased remarkably over time in comparison to the baseline (p = 0.001). Overall the response rate was 88% at the end of 12 weeks and 85% at the end of 24 weeks. The drug was found more effective with a quicker response in cyclic pattern of matalgia. Complete response was observed in 66% of cyclic mastalgia and 40% of noncyclic mastalgia patients at 1 week of therapy. The response was improved over time in both groups and at completion of treatment (12 weeks) 92% patients in cyclic group and 80% patients in noncyclic group were pain free. The effect of the drug persisted till the completion (24 weeks) of the study (p = 0.001). These results imply that centchroman is very effective in treating breast pain and can be prescribed as drug of first choice for mastalgia.
