OBJECTIVETo study the clinicopathological features of primary squamous cell carcinoma (SCC) of breast and the diagnosis and treatment of the disease.

METHODSThe clinical, operative and pathological data from 7 cases of SCC of breast were retrospectively analysed.

RESULTSFive patients complained of painless mass and two of them were accompanied with local pain. All patients were diagnosed as having SCC by fine-needle aspiration before operation. Two patients underwent modified radical mastectomy, and the others received radical mastectomy. Pathological examination showed primary squamous cell carcinoma of the breast with metastasis to axlliary lymph nodes in one patient. Follow-up of four patients revealed that two patients are living well and two patients died. Three patients lost to follow up.

CONCLUSIONThe diagnosis of primary squamous cell carcinoma of the breast is dependent on pathological results. Radical mastectomy including modified radical mastectomy is most effective in the treatment of mammary SCC. Postoperative chemotherapy and radiation are necessary auxiliary therapy.

OBJECTIVES: To investigate the clinical and pathological features of patients with unilateral sinonasal disease (USD). METHODS: A retrospective analysis was completed on 376 adult patients with USD from January 2015 to December 2016. Their presenting symptoms, nasal endoscope, CT scanning, and pathology were analyzed respectively. RESULTS: Among the 267 (71.01%) patients with inflammatory disease, there were 4 pathological types. And there were 8 pathological types in 60 (15.96%) patients with benign tumor. Of the 49 patients with malignant tumor, there were 15 pathological types which included squamous carcinoma, malignant melanoma, and lymphoma, as well as myoepithelial carcinoma and Mesodermal mesoderm. The onset age of inflammation group was younger than that of benign (<0.05) or malignant tumor groups (<0.05). The misdiagnosis rate was 8.33% in benign tumor (5/60), and 10.20% in malignant tumor (5/49). Nasal polyps was the most common misdiagnosis in the groups of benign and malignant tumor. CONCLUSIONS The pathology of adult patients with USD is complicated, and no specific clinical feature was found for distinguishing between benign and malignant lesions. The tumor took a quite proportion in adult patients with USD. Therefore, careful consideration should be taken before diagnosing patients with USD in order to reduce misdiagnosis rate.

Dermatomyositis (DM) is an uncommon inflammatory myopathy with characteristic rash accompanying, or more often preceding, muscle weakness. There is a well-recognized association between DM and several cancers, such as ovarian cancer, breast cancer, melanoma, colon cancer, and non-Hodgkin lymphoma. We report the first case of cancer of unknown primary site associated with DM. A 62-yr-old woman presented to us with both shoulder painful swelling and facial edema. She was diagnosed previously as cancer of unknown primary site, histologically confirmed with squamous cell carcinoma in a pelvic mass. For the following days, she complained of erythematous face followed by progressive weakness of the proximal muscles of upper and lower limbs. The laboratory tests showed an increased muscle enzyme and acute phase reactants. The electromyogram showed the typical findings of DM. After the treatment with high dose steroid and methotrexate, the proximal motor weakness improved, and she received palliative radiation therapy.

Esophageal cancer is the 7th leading cause of cancer deaths worldwide. While squamous cell carcinoma is the most prevalent histology internationally, adenocarcinoma of the distal esophagus accounts for nearly 50% of cases in developed countries due to the differences in the etiologic factors such as gastroesophageal reflux disease (GERD) and obesity that predominate. While surgery is the mainstay of treatment of this disease, the utilization of chemoradiation, either used postoperatively or neoadjuvantly, has become a standard practice in the United States. What is the optimal management approach is still an area of contention, however, and may be different in different regions around the world. This article reviews some of these controversies, including the role for surgery in patients treated with definitive chemoradiation. At the end, we will also outline recommendations regarding radiotherapy procedures and techniques.

We report successful outcomes after endovascular placement of a stent graft in a 74- and a 77-year-old men, both of whom had malignant superior vena cava syndrome caused by squamous cell carcinoma. In each patient, successful palliation of the malignant superior vena cava syndrome was achieved by placement of a stent graft. No procedure-related complications were observed. The patients were asymptomatic until their deaths, seven and 14 months after stent graft placement, respectively.

Azathioprine (AZA) treatment in transplant or autoimmune patients and subsequent appearance squamous cell carcinomas at various sites, particularly skin and cervix, has shown a close relationship. However, it remains uncertain whether this is true for the patients with Crohn's disease. We report a case of squamous cell carcinoma of the breast occurred in a 35-year-old female with Crohn's disease taking AZA. She was first diagnosed with Crohn's disease 10 years ago and has taken AZA with 5-aminosalicylic acid (5-ASA) on regular follow up in gastrointestinal department for 9 years. She had no family history of breast cancer. She visited breast cancer clinic due to incidentally found right breast mass. A mastectomy on the right breast was performed and 6.3x5.5 cm mass was removed. The mass was microscopically proven to be poorly differentiated squamous cell carcinoma with focal keratin pearl formation. At age of 25, she was first diagnosed with active Crohn's disease. 5-ASA and corticosteroid induced remission. Then, steroid was tapered off and AZA was maintained at 1 mg/kg due to leukopenia at higher dose. She stopped taking AZA at her discretion during her two pregnancies and reported total of 67 months of AZA medication on her breast cancer diagnosis.

Due to the advanced diagnostic technique and better understanding for multiple primary lung cancers (MPLC), the increasing incidence of MPLC has been reported. Very often, MPLC are misdiagnosed as metastasis because of lacking efficient molecular biomarkers for prediction and diagnosis. Studies on the molecular mechanism for tumorgenesis and progression of MPLC may therefore facilitate the discovery of biomarkers for disease diagnosis and prognosis, so that an individual and rational treatment can be achieved. We tried to further our understanding and improve the diagnostic skill for MPLC by reviewing the current status and the latest advancement of molecular markers related to MPLC.

OBJECTIVETo investigate the clinical application of diffusion weighted imaging (DWI) in uterine cervical cancer and the apparent diffusion coefficient (ADC) value in diagnosis and predicting treatment response.

METHODSTwenty-eight patients with advanced primary cervical cancer confirmed by pathology and 10 cases of normal uterine cervix as control were recruited in this prospective clinical trial. To analyze the correlation between tumor volume measured in DWI and tumor maximum diameter measured according to the RECIST criteria. To compare the ADC value differences among the uterine cervical cancer, uterine myometrium, and normal uterine cervix. To compare the ADC values in 17 cancer patients before and after treatment.

RESULTSThe illustration of tumor boundary in DWI was superior to conventional T2WI and post-enhancement T1WI. The DWI with higher b value (2000 s/mm(2)) had a better signal-to-noise ratio. The tumor volume measured in DWI has good correlation with tumor maximum diameter according to RECIST criteria (r = 0.759, P < 0.01). When b = 800 s/mm(2), the ADC values of the uterine cervical cancer, uterine myometrium, and normal uterine cervix were (9.85 ± 1.55)×10(-3) mm(2)/s, (14.20 ± 2.80)×10(-3) mm(2)/s, and (14.14 ± 0.45) ×10(-3) mm(2)/s. When b = 2000 s/mm(2), the ADC values of the uterine cervical cancer, uterine myometrium and normal uterine cervix were (7.38 ± 0.98)×10(-3) mm(2)/s, (8.52 ± 2.38)×10(-3) mm(2)/s, and (8.60 ± 0.63)×10(-3) mm(2)/s, respectively. There were significant differences between the cervical cancer and normal cervix or uterine myometrium (P < 0.001 for both). When b = 800 s/mm(2), the ADC value was (9.85 ± 1.55)×110(-3) mm(2)/s before and (13.41 ± 2.93)×10(-3) mm(2)/s after treatment (P < 0.001). When b = 2000 s/mm(2), the ADC value was (7.38 ± 0.98)×10(-3) mm(2)/s before and (8.93 ± 1.92)×10(-3) mm(2)/s after treatment (P = 0.008). Univariate logistic regression analysis showed that 25% ADC, 50%ADC, and 75%ADC in the tumor ADC value histogram before treatment were significantly correlated to the treatment outcome of cervical cancer (P < 0.05 for all). Multivariate regression analysis showed that 25%ADC, 50%ADC, and 75%ADC in the tumor ADC value histogram before treatment were not significantly correlated to the treatment outcome of cervical cancer (P > 0.05 for all). The values of ROC curves were 25%ADC = 0.818, 50%ADC = 0.775, and 75%ADC = 0.716 (P > 0.05), however, the 25% ADC showed a relatively stronger statistical power.

CONCLUSIONSDWI helps to confirm the morphology and exact target zone of the tumor for radiotherapy. DWI volume measurement is well correlated with RECIST criteria, particularly in volume measurement of irregular tumors. ADC value has a potential in quantitatively monitoring treatment response and predicting outcome of cervical cancers.

Esophageal carcinosarcoma is a rare malignant esophageal neoplasm consisting of both carcinomatous and sarcomatous elements, with an incidence of 0.5%. There have been only a few case reports of carcinosarcoma and squamous cell carcinoma coexisting in the esophagus. However, all of these are cases of synchronous or metachronous development of carcinosarcoma after chemoradiotherapy in patients of esophageal squamous cell carcinoma. A 53-year-old man underwent esophagogastroduodenoscopy because of chest pain for several months. Endoscopic examination revealed a huge pedunculated esophageal polypoid mass. Endoscopic submucosal dissection (ESD) was performed and histopathologic examination confirmed spindle cell carcinoma (carcinosarcoma). He refused additional esophagectomy. After 21 months, third follow-up endoscopy showed poorly-demarcated flat, faint discolored lesions at different location from the previous ESD site and endoscopic biopsies confirmed squamous cell carcinoma. To the best of our knowledge, this is the first case of metachronous development of esophageal squamous cell carcinoma in a patient with esophageal carcinosarcoma.
