Design of a cylindrical brachytherapy implant applicator for the irradiation of an intestinal segment in mice.

YingExperimental determination of the RBE of new isotopes for brachytherapy implants (e.g. iodine-125 and palladium-103) remains a very difficult problem, especially in small animals, where the seeds cannot be implanted easily in the planned geometry in a reproducible way.

[Cytoreductive surgery in the management of stage IV epithelial ovarian cancer].

Objective: To determine the role of cytoreductive surgery in patients with stage IV epithelial ovarian cancer.

Methods: From Jan. 1986 to Dec.

[Nucleoside diphosphate kinase/nm23H1 expression in ovarian epithelial carcinoma: retroperitoneal lymphatic metastasis and survival].

Objective: To determine the relationship between NDPK(A) expression and retroperitoneal lymph node metastasis (LNM) and the significance of the prognosis in epithelial ovarian carcinoma.

Methods: NDPK(A) expression of formalin-fixed parafin-beded samples, which included 74 primary, 31 intraperitoneal and 18 retroperitoneal lymph node metastatic tumors, were examined by ABC immunohistochemisty in 74 patients with primary ovarian cancer.

Results: In the 74 primary lesions, 22 samples showed positive staining of NDPK(A) (30%).

[Factors affecting prognosis of papillary thyroid carcinoma with bilateral cervical lymph node metastases].

One hundred thirty nine cases of papillary thyroid carcinoma with bilateral lymph node metastases were reviewed. They were surgically treated at the Cancer Hospital of Shanghai Medical University in the years from 1956 through 1990. There were 73 men and 66 women with a median age of 35 (range 11-70) years.

[A clinical study on the incidence of retroperitoneal lymph node metastasis and its risk factors in ovarian cancer].

Objective: To investigate the incidence and the significant risk factors of retroperitoneal lymph node metastasis (LNM) in primary ovarian cancer for considering the necessity of systematic lymphadenectomy.

Methods: 117 cases of retroperitoneal lymphadenectomy performed on primary ovarian cancers in our hospital from November, 1987 to January, 1994 were studied. The relationship between clinicopathologic characters and the incidence of LNM were determined by univariate and multivariate analysis.

[The surgical treatment of gastric stump cancer: an analysis of 26 cases].

26 patients with gastric stump cancer were treated by surgery plus chemotherapy or radiotherapy in our hospital from 1970 to 1992. 20 patients were qubiected to surgery plus chemotherapy 12 patients were operable six patients had simple radiotherapy. These patients were followed up to the end of 1992.

[The value of Sm-153-EDTMP for treatment of metastatic bone pain and improving quality of life].

Sm-153-EDTMP (ethylenediaminetetramethylene phosphonic acid), a beta-particle and gamma-emitting radionuclide, was used for pain control of bone metastasis. Fourty patients with bone metastasis were administrated a single intravenous injection of 29.6 MBq/kg (0.

[Anaplastic carcinoma of the thyroid: an analysis of 33 cases].

Thirty-three patients with anaplastic carcinoma of the thyroid were treated during the past 30 years with 27 cases of simple anaplastic carcinoma and the other 6 found also with some differentiated carcinoma component. survival rate of 3.5 and 10 years were 35.

[Occult carcinoma of the thyroid].

We reviewed the clinical and pathologic data of the 135 cases with occult carcinoma of the thyroid (OCT) between 1962 and 1991. 54 cases were found incidental to thyroid operation (group I), 77 cases were found primarily by cervical node metastasis (group II), 3 were found at the time of operation for other tumors of the head and neck and 1 was traced by distant metastasis. All patients were treated surgically in our service.

[10 years' experience on infrahyoid myocutaneous flap].

From May 1979 to December 1989, 260 infrahyoid myocutaneous flaps (IHMCFs) were used for reconstruction after resection of head and neck cancer in one stage. It has been certified that the IHMCF is a reliable versatile and convenient island myocutaneous flap, suitable for repairing the defect in the oral cavity, parotid region, oro- or hypopharynx particularly the tongue after hemi-excision of oral tongue to radical total glossectomy. The success rate of the IHMCF may be increased to 97% if the following points are noticed.
