Background: Neoadjuvant chemotherapy (NACT) is used to treat advanced or irreversible breast cancer tumors and increases the possibility of Breast-conserving surgery. There is evidence that pathological complete response (pCR) after NACT reduces the risk of recurrence and increases survival.
Objectives: This study aimed to investigate the factors affecting the pathological complete response in breast cancer patients treated with NACT.
Methods: We identified non-metastatic breast cancer patients receiving NACT during 2010–2020. Patients’ and disease characteristics, rates of pCR based on these characteristics were recorded in different subgroups. Analyzes were performed by descriptive and analytical statistics using SPSS.ver26.
Results: 204 patients had mean age of 45.3 years, 32.4% had grade 3, and 89.7% had ductal histology. Overall pCR rate was 33.3% and differed according to disease subtype (p<0.001), receptor status (p<0.001), grade (p=0.015), ki-67 (p=0.004), but not according to age, BMI, menopausal status, tumor size, surgery type after NACT.
Conclusion: In our study, pCR rates are conformed with other studies. Many patients have residual disease following NACT that suggests lower survival or higher risk of recurrence, therefore determining the factors affecting the pathological complete response can help physicians in treatment decisions.

Background & Objective: Immunosuppression, HPV persistence, and smoking are the main related risk factors of cervical intraepithelial neoplasia (CIN) recurrence. However, age as a basic factor may be a main factor related to CIN recurrence. Therefore, our study aimed to detect the potential role of women's age in CIN recurrence.Materials & Methods: This cross-sectional study was conducted on 329 patients who underwent conization in the gynecology-oncology clinics of Arash and Imam Khomeini hospitals affiliated with Tehran University of Medical Sciences between February 2016 and February 2021.Results: Totally, 329 cases were enrolled in the study. Most women were in their thirties. CIN recurrence was about 10.0% (32 cases). The CIN recurrence rate was 8.9% in women younger than 30, 10.2% in 30-40, 11.3% in 40-50, and 5.6% in 50-60 decades. There was no significant (p-value=0.802) difference in recurrence rate among age groups. There was a significant (p-value=0.023) difference in the frequency of endocervical involvement regarding age category, women aged 40 to 50 had the most frequent marginal involvement with 26.8%, while there was no significant (p-value=0.802) difference in frequency of marginal involvement regards age category.Conclusion: CIN cases with age higher than 40 years need to have more caution and tight follow-up visit after conization.

Breast cancer (BC) was the most common cancer in Iran, accounting for 12.9% of all incident cancer, and was the 5th leading cause of cancer death in 2020. The latest age standardized incidence rate (ASIR) of breast cancer was 35.8 in Iran and is expected to increase to more than 70 per 100,000 by the end of 2030. Incidence of breast cancer had a clustering pattern in Iran, while central provinces had the highest ASIR (72 per 100,000 population), and South East provinces had the lowest ASIR (5-11 per 100,000 population). Numerous studies have shown that the peak incidence of breast cancer was occurred in the age group of 40-49 years in Iran. There has also been reported a rapid increase in the incidence in young women from different regions of the country. Known molecular and cellular processes involved in the development of breast cancer in Iranian BCs have been reported from various studies in recent decades, and the most well-known and prominent genes susceptible to breast cancer were BRCA1 and BRCA2. They acted as tumor suppressor genes and inherited mutations leading to chromosomal instability. However, non-coding RNAs, epigenetic alterations, signaling pathways, immune responses, and antioxidant-related genes are the main molecular processes associated with the progression of breast cancer among Iranian patients. While we are facing a significant increase in the incidence of breast cancer, with a lower survival rate, breast cancer is currently considered as one of the major health problems in Iran, which emphasizes the importance of providing and designing prevention and early detection program of breast cancer.

Background & Objective: Breast cancer has a pivotal role in many deaths caused by malignancies. Epidermal growth factor receptor-2 (EGFR-2 or HER-2) and estrogen receptor (ER) have immense predictive values as prognostic factors. Breast cancers that have steroid receptors and respond to hormone therapy show a better prognosis than cancers without steroid receptors.Materials & Methods: A retrospective cross-sectional study was performed on 500 pathology blocks of women with breast cancer sent to the pathology department of Amir-al-Momenin medical and educational center, Gerash, Iran, from 2016 to 2019. Data were analyzed by SPSS software (Version-16) via ANOVA test followed by Chi-square and t-tests. P-value <0.05 was considered as significant.Results: The utmost type of malignancy was invasive ductal carcinoma (IDC) at 35.03%. Among ER-positive patients 59.67% were HER-2-positive. Nonetheless, among the PR-positive patients 54.74% were HER-2-positive. ER-positive patients were correlated with p53 receptor, distant metastasis and HER-2 significantly (P < /i><0.01). However, PR-positive patients just correlated with p53 receptor significantly (P < /i><0.01).Conclusion: Investigated samples were more ER-negative and less PR-positive compared to similar studies. Meanwhile, ER-positive patients were HER-2-positive. Regarding the correlation with prognosis of breast cancer, especially in HER-2-positive patients, there is a need to perform profound screening programs for HER-2 in breast cancer patients, especially with histopathological characteristics of invasive ductal carcinoma.

Due to its rarity, the standard clinical presentation, treatment protocol, and prognosis of primitive neuroectodermal tumor (PNET) have not been clearly described yet. Hence, herein we reported a case of ovarian peripheral PNET whose histomorphology reports caused her certain diagnoses at Imam Khomeini Hospital, affiliated to Tehran University of Medical Sciences, Tehran, Iran, in 2020.Considering different clinical presentations, and poor prognosis of PNET compared to other ovarian malignancies, to on-time diagnosis and treatment, the patient's histomorphology and immunohistochemical (IHC) profile assessment, particularly in younger women, seems beneficial.

Laparoscopy is a surgical procedure which has been used in gynecologic cancer since 1994. With technology progressing during years, there are so many kinds of minimally invasive surgeries in gynecologic malignancies. Regarding the importance of overall survival and progression of free survival in cancerous patients, we should consider this type of surgery very wisely not to compromise patient's prognosis. Considering all the points above, a review was performed to study the role of laparoscopy in gynecologic oncology including endometrial and cervical cancer. It can be concluded that laparoscopy is not safe in a disease with high risk of tumor spread. Also a good prognosis of cancer patients should not be jeopardized by doing incomplete laparoscopic surgery.
