Thyroid-like low-grade papillary adenocarcinoma of nasopharynx.

We report a 35-year-old woman with complaints of nasal obstruction and mild post-nasal drip for 6 months. She did not improve with medical treatment. Clinical examination had no positive finding.

Predictors of Pathological Complete Response to Neoadjuvant Chemotherapy in Iranian Breast Cancer Patients.

Background: Achievement of pathologic complete response (pCR) in breast cancer patients receiving neoadjuvant chemotherapy (NAC) is associated with both overall survival and disease-free survival. The aim of present study was to identify clinical and pathological factors associated with achieving pCR in Iranian breast cancer patients receiving NAC. Methods: A retrospective review of all breast cancer patients treated with neoadjuvant chemotherapy between April 2012 and September 2016 at our institution was performed; 207 cases were evaluable for analysis.

Long-term complete remission of a patient with high grade neuroendocrine carcinoma of ampulla of Vater.

We describe a case report of a 53-year-old man with a 5-months history of progressive jaundice and upper abdominal pain. The patient was further evaluated and finally diagnosed with a high-grade ampullary neuroendocrine tumour (based on endoscopic-guided biopsy). Thereafter, he underwent pancreatoduodenectomy and adjuvant platinum-based chemotherapy.

Frequency and Predictors of Axillary Lymph Node Metastases in Iranian Women with Early Breast Cancer.

Background: Axillary lymph node metastasis is the most important predictive factor for recurrence risk and survival in patients with invasive breast carcinoma. The aim of this study was to determine factors associated with metastatic involvement of axillary lymph nodes in Iranian women with early breast cancer. Methods: This article reports a retrospective study of 774 patients with T1-T2 breast cancer who underwent resection of the primary tumor and axillary staging by SLNB and/or ALND between 2005 and 2015 at our institution.

Epidemiology of Neuroendocrine Tumors in an Iranian Population.

Neuroendocrine tumors (NETs) are a rare and heterogeneous group of malignancies most commonly found in the gastrointestinal system. In this study, we examined the epidemiology of NETs in an Iranian population. The incident NET cases diagnosed between January 1, 2009 and December 31, 2014 were collected from databases of three hospitals in Tehran (Shoada-e-Tajrish Hospital, Imam Hossein Hospital and Pars Hospital).

Conservative treatment in young patients with cervical cancer: a review.

For cervical cancer cases with a low risk of relapse who wish to maintain their fertility, radical trachelectomy is an alternative to radical hysterectomy. Pelvic magnetic resonance imaging is recommended before surgery, with laparoscopic assisted lymphatic dissection required for assessment of lymphatic metastasis. If there is a visible lesion in the cervix, the specimen taken during trachelectomy should be sent for frozen section.
