Colorectal carcinoma in childhood and adolescence: a clinicopathologic review.

Purpose: Pediatric colorectal carcinoma (CRC) is rare, but the available data suggest that it is more likely than adult CRC to be advanced at presentation and to have a poor outcome. We sought to better characterize pediatric CRC.

Patients And Methods: We reviewed the clinical and pathologic features, prognostic factors, and outcome of CRC in 77 children and adolescents (ages 7 to 19 years) referred to St Jude Children's Research Hospital between 1964 and 2003.

Concomitant administration of vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide for high-risk sarcomas: the St. Jude Children's Research Hospital experience.

Background: Intensified chemotherapy may improve the outcome of patients with high-risk pediatric sarcomas. Vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide are highly effective against pediatric sarcomas. The authors investigated the feasibility of administering these agents concomitantly within a defined period.

Metastatic osteosarcoma.

Background: The outcome of patients with metastatic osteosarcoma treated in two consecutive trials from 1986 to 1997 was analyzed to evaluate the efficacy of carboplatin-based multiagent chemotherapy and to identify prognostic factors. The initial study (OS-86) used ifosfamide, cisplatin, doxorubicin, and high-dose methotrexate, and the subsequent study (OS-91) used the same agents at similar doses, but carboplatin was substituted for cisplatin.

Methods: Twelve patients (median age, 15.

The feasibility of adjuvant interferon alpha-2b in children with high-risk melanoma.

Background: It has been shown that induction high-dose interferon alpha-2b (IFN-alpha-2b) followed by maintenance therapy improves recurrence-free survival in adults with high-risk, resected melanoma. In this study, the feasibility and toxicity of this regimen were evaluated in newly diagnosed pediatric patients with Stage III melanoma involving regional lymph nodes.

Brain metastases of malignant germ cell tumors in children and adolescents.

Background: Brain metastases of pediatric germ cell tumors are uncommon, and there is limited information regarding their incidence, clinical presentation, response to treatment, and influence on survival.

Methods: The authors reviewed the experience with brain metastases from pediatric germ cell tumors at St. Jude Children's Research Hospital (Memphis, TN) over a 40-year period.

Real-time polymerase chain reaction as an aid for the detection of SYT-SSX1 and SYT-SSX2 transcripts in fresh and archival pediatric synovial sarcoma specimens: report of 25 cases from St. Jude Children's Research Hospital.

Synovial sarcoma is the most common nonrhabdomyosarcomatous soft tissue sarcoma in children and adolescents and is characterized by a reciprocal t(X;18)(p11;q11) which results in the fusion of the SYT gene on chromosome 18q11 to either of two closely related genes, SSX1 (Xp11.23) or SSX2 (Xp11.21).

Clinical features and outcome of initially unresected nonmetastatic pediatric nonrhabdomyosarcoma soft tissue sarcoma.

Purpose: To describe the clinical features, response to therapy, and outcome of pediatric patients with initially unresected nonmetastatic nonrhabdomyosarcoma soft tissue sarcoma (NRSTS).

Patients And Methods: We retrospectively reviewed the presenting clinical features and tumor characteristics of all 40 pediatric patients with initially unresected nonmetastatic NRSTS who were seen at our institution between March 1962 and December 1996. A subset of 27 patients for whom complete treatment information was available was analyzed to determine whether response to therapy was associated with local disease control and event-free and overall survival.
