Basaloid squamous cell carcinoma of the uterine cervix is an extremely rare malignancy of the female genital tract with a poorer clinical outcome than squamous cell carcinoma of the uterine cervix. We report a case of pure basaloid squamous cell carcinoma of the uterine cervix. A 70-yr-old woman with vaginal bleeding was referred to our institute. A basaloid squamous cell carcinoma of the uterine cervix, of International Federation of Gynecology and Obstetrics (FIGO) stage Ib1, was diagnosed by a loop electrosurgical excision procedure cone biopsy. A radical hysterectomy was performed, along with bilateral salpingo-oophorectomy, pelvic lymph node dissection, and para-aortic lymph node sampling. Pathologic findings were consistent with a basaloid squamous cell carcinoma confined to the cervix without an extracervical tumor. No further treatment was administered and there was no clinical evidence of recurrence during the 12 months of follow-up. Follow-up for the patient is ongoing. Although basaloid squamous cell carcinoma of the uterine cervix is thought to behave aggressively, accumulation of data on these rare tumors is necessary to determine whether their behavior differs significantly from that of conventional cervical squamous cell carcinoma of similar clinical stage. These data would be useful for defining the best diagnosis and treatment for these rare tumors.

Sinonasal inverted papilloma (SNIP) is one of the most common benign sinonasal tumors demonstrating a high recurrence rate after surgery, and sometimes presents malignant tendency or coexists squamous cell carcinoma. Therefore, it is essential to achieve complete surgical resection, especially the original location of SNIP. In this paper, we evaluated the predictability of preoperative CT and magnetic resonance imaging (MRI) for localization of SNIP origin.

OBJECTIVE: To analyze the diagnosis, therapy and prognosis of the rare cases of malignant tumors in external auditory canal. METHOD: Eight cases of rare malignant tumors in external auditory canal were collected except squamous cell carcinoma and adenoid cystic carcinoma. The clinical manifestation, staging, surgical method, secondary treatment and prognosis were analysed. RESULT: There were 5 cases of basal cell carcinoma and 2 cases of mucoepidermoid carcinoma and 1 case of myoepithelial carcinoma. Three cases of the 5 basal cell carcinoma in external auditory canal have been misdiagnosed for a long time. After admission, 4 of the 5 basal cell carcinoma were T1 stage and cured only by a complete resection of tumor. One case of T2 stage basal cell carcinoma was found recurrence 2 years later after the first excision of tumor, and was treated with radiotherapy. Tumor was controlled. Two cases of mucoepidermoid carcinoma had been misdiagnosed as a benign tumor and received a resection. One case was found metastasis to the parapharyngeal space and nasopharynx and was treated with concurrent chemotherapy. Tumor was also controlled after 5-years follow-up. Another case was found metastasis to parotid gland and received an expanding tumor resection. No recurrence was detected after a 1-year followed up. One case of T4 stage myoepithelial carcinoma in external auditory canal was a metastasis of parotid and received a partial temporal bone resection. No-recurrence was found 1 year later. CONCLUSION Because the tumors above have a very low incidence in external ear canal and the location of tumors are hidden, they are often misdiagnosed and delayed in treatment. Therefore, otologists should pay more attention to avoid the misdiagnosis. To the treatment, complete surgical resection of early-stage tumor is important and for late-stage tumor, a supplemented by chemoradiotherapy may be needed.

OBJECTIVETo investigate the pattern of early lymph node metastasis of thoracic esophageal squamous cell carcinoma and its prognostic value.

METHODSClinical and follow-up data of 126 patients with pathological stage pN1 of esophageal squamous cell carcinoma undergoing radical esophagectomy in our department from January 2005 to December 2008 were analyzed retrospectively. Impact of lymph node metastasis pattern on prognosis was investigated.

RESULTSThe relatively common sites of lymph node metastasis were upper mediastinum(53.8%), middle and lower thoracic paraesophageal(38.3%), right and left cardiac(34.4%) and the left gastric artery(36.8%). Univariate analysis showed that the lymph node metastasis of subcarinal, middle and lower thoracic paraesophageal and the left gastric artery was associated with 5-year survival rate. Multivariate analysis revealed that the presence of subcarinal and middle and lower thoracic paraesophagea lymph node metastasis was an independent risk factor of survival.

CONCLUSIONSUpper mediastinal, middle and lower thoracic paraesophageal, right and left cardiac and the left gastric artery are the earliest lymph node metastasis sites of esophageal squamous cell carcinoma. The presence of subcarinal and middle and lower thoracic paraesophagea lymph node metastasis is an independent risk factor of survival. Patient prognosis should be analyzed with lymph node metastasis pattern based on the 7th edition UICC-AJCC TNM classification system.

OBJECTIVE: To investigate the clinical and pathological characteristics of sinonasal neoplasms. METHOD: A cohort of 333 patients with sinonasal neoplasm, which were confirmed by surgical pathology, were enrolled in this study. The clinicopathological characteristics, in terms of age, sex, location, and disease constituent ratio were retrospectively reviewed. RESULT: (1) In this series of patients, there were 200 males and 133 females, aged from 2 to 84 years, with a median of 54 years. The benign to malignant ratio was 1.1:1. As for their origination, 144 tumors arose from the nasal cavity, while, 191 tumors derived from sinus, including 90 from maxillary sinus, 31 from frontal sinus, 46 from ethmoid sinus, and 24 from sphenoidal sinus. (2) Disease constituent ratio decreased in order of epithelial tissue, soft tissue, lymphohematopoietic tissue, bone and cartilaginous tissue, ectopic intracranial tumors. The five most frequent malignant tumors were squamous carcinoma, lymphoma, adenoid cystic carcinoma, malignant melanoma and esthesioneuroblastoma, while, benign tumors ranked in the top five were papilloma, fibroma, osteoma, angioma and ectopic intracranial tumors,respectively. (3) Of 200 cases arising from epithelium, 118 were benign, 82 were malignant, and the benign to malignant ratio was 1.4:1. Of 68 cases from soft tissue, 37 were benign and 31 were malignant tumors (ratio, 1.2:1). Among the 22 cases from bone and cartilaginous tissue, 17 were benign and 5 were malignant (ratio, 3.4:1). With respect to the 29 cases from lymphohematopoietic tissue, the majority of tumors were malignant (28 cases), with only one benign case. In addition, ectopic intracranial tumors were also observed. Besides the above all, 12 cases of other types were found in this work. CONCLUSION Neoplasms from different parts of nasal cavity and paranasal sinus have specific clinical characteristics. The pathological types of these tumors may be highly diverged. The diagnosis and differential diagnosis depend mainly on pathological examination. Comprehensive treatment, which employs surgery in combination with other modalities, is the main strategy for these tumors.

OBJECTIVESTo analyze associated factors and the prognosis of patients with residual cancer after esophagectomy for squamous cell carcinoma of the esophagus, and to assess outcomes after salvage treatment.

METHODSClinical and pathological data of 1074 patients with squamous cell carcinoma of the esophagus who underwent esophagectomy in the Cancer Center of Sun Yat-sen University from 1997 to 2003 were analyzed retrospectively. The relationship between the associated factors (differentiation, location, length of the lesion, surgical route, anastomosis site, T stage, N stage) and the incidence of residual cancer was analyzed, using the chi-squared test and Logistic regression analysis methods. The value and the modality of the salvage treatment were investigated.

RESULTSForty-four patients had residual cancer (4.3%). Cancers in the upper esophagus were associated with the highest incidence of residual cancer on esophageal stump (6.5%), while the lower esophagus had the highest incidence of residual cancer on gastric stump (0.78%). The Incidence correlated with T and N stage. Logistic regression analysis showed that T and N stage were the risk factors of residual cancer. Three-year survival rate was 22.7% in patients with residual cancer. The mean survival time was 25.2+/-3.3 months. Three-year survival rates of patients with and without salvage treatment were 53.2% and 7.8%, respectively (P=0.027). Three-year survival rate of patients with salvage radiotherapy was 56.0%.

CONCLUSIONSAdvanced T and N stage are the risk factors of residual cancer after esophagectomy in the patients with squamous cell carcinoma of the esophagus. Salvage treatment can improve the survival of the patients.
