Object. The optimum clinical management of central nervous system (CNS) teratomas, particularly postsurgical adjuvant therapy, is still unclear, partly as a result of the tumors' low incidence. In this study the authors analyze 34 cases of CNS teratomas so that they may adequately indicate management of these lesions. Methods. The median age of the 34 patients was 13 years. Twenty-seven patients treated between 1970 and 1991 were retrospectively reviewed. Four of these 27 patients died as a result of radical surgery; each of them had a teratoma involving the hypothalamus. After initial treatment, which included radiation therapy, 20 patients (48%) had died. In all seven cases of mature teratomas there was no recurrence. In two cases of immature teratomas in which there was complete surgical resection there was recurrence; however, salvage therapies were effective. Seven of eight patients with highly malignant teratomas died; for these patients salvage therapies, including repeated radiation and chemotherapy, failed. Seven patients who presented with CNS teratomas between 1992 and 1996 received adjuvant chemotherapy and radiation therapy according to a prospective study protocol. All seven patients were free from recurrence with a 70 to 100% Karnofsky Performance Scale score at a median follow-up period of 41 months. Patients with CNS teratomas rarely responded completely to chemotherapy or radiation therapy; an effective adjuvant therapy produced a partial response at best. Conclusions. Because teratomas show various responses to adjuvant therapy, a misdiagnosis of their histological subtype will lead to inadequate therapy. A diverse therapeutic protocol based on histological diagnosis is necessary to plan appropriate management. Treatment recommendations are discussed in detail in the article.

Radiation therapy remains an important component of lymphoma treatment. It has evolved with improvements in technology and a better understanding of how to successfully integrate it into lymphoma treatment. There are specific clinical presentations where omission of radiation therapy could adversely affect patient outcome and should not be overlooked. Radiation therapy may serve an important role as primary treatment, as a component of combined modality therapy, as adjuvant therapy to maximize local control, and as an important component of salvage therapy for relapsed or primary refractory lymphoma and in the successful palliation of lymphoma. This review identifies those clinical presentations where the use of radiation therapy should not be overlooked or should at least be considered.

Salvage Radiation Therapy

367 Background: SWOG 8794 recommends adjuvant radiation therapy (ART) after radical prostatectomy (RP) for T3 and/or positive margins. Our purpose was to assess 12-year outcomes on 862 RP patients who had either T3 and/or positive margins who underwent surveillance, salvage radiation therapy (SRT), or hormonal therapy (HT), while categorizing these patients into very low risk (VLR), low risk (LR), high risk (HR), and ultra high risk (UHR) groups. Methods: From 2004 - 2007, 862 RP patients had adverse factors of extracapsular penetration (T3a), seminal vesicle invasion (T3b), positive margins, and/or detectable post-operative PSA. Management included surveillance (54.8%), SRT (36.8%), and HT (8.5%) as first salvage therapy, and 21.5% eventually received hormonal therapy. Twenty patients underwent ART, and were excluded from this analysis. We assessed prognostic factors using multivariable analysis, and 12-year estimates of freedom from biochemical failure (FFBF), freedom from salvage therapy (FFST), distant metastases-free survival (DMFS), prostate cancer-specific survival (PCSS), and overall survival (OS). VLR were those with Gleason Score (GS) of 6. LR were GS 3+4 with only T3a or positive margins, but an undetectable postoperative PSA <0.1. HR were T3b with GS 7-10, any GS 7-10 with T3a/b and positive margins, but an undetectable PSA. UHR were those with a detectable PSA with a GS 7-10. Results: Median follow-up was 12.1 years. Median age was 61.6 years. Median time to first salvage treatment for VLR, LR, HR, and UHR were 10.8, 11.1, 5.3, and 0.6 years, p<0.001. 12-year estimates of FFBF for VLR, LR, HR, and UHR were 60.2%, 52.9%, 28.4%, and 0%, p<0.0001. For FFST, 70.9%, 68.6%, 40.5%, and 0%, p<0.0001. For DMFS, 99.1%, 97.8%, 88.6%, and 63.6%, p<0.0001. For PCSS, 99.4%, 99.5%, 93.5%, and 78.9%, p<0.0001. For OS, 91.8%, 91.8%, 81.0%, and 69.9%, p<0.0001. Conclusions: Outcomes of T3 and/or positive margins using surveillance or SRT as initial management yields excellent outcomes for VLR and LR groups, in which ART should be avoided. For HR, ART can be considered reasonable, since FFBF is only 28.4%. For VHR, these patients may benefit from combined hormonal therapy and ART.

Salvage Radical Prostatectomy

Patients with isolated local recurrence of prostate cancer after radiation therapy may potentially be cured of their disease by salvage radical prostatectomy (RP). The stage-specific 5-year cancer-control rates of salvage RP resemble those of standard RP. However, the ability to effectively administer salvage treatment to patients with radiorecurrent disease is compromised by the lack of diagnostic tests with sufficient sensitivity and specificity to detect local recurrence at an early stage while it is amenable to local salvage therapy. By the time biochemical recurrence is declared using the current American Society for Therapeutic Radiology and Oncology definition, the majority of patients have advanced local disease, precluding successful local salvage therapy. When salvage RP is performed at prostate-specific antigen levels of 10 ng/mL or less, an estimated 70% of patients are free of disease at 5 years. With better patient selection and technical modifications, the morbidity associated with salvage RP has improved substantially. Rates of urinary incontinence and anastomotic stricture are acceptable, although one third of patients will experience these complications. Salvage cryotherapy is a minimally invasive alternative to salvage RP, but cancer-control rates appear to be inferior and it does not provide a clear advantage over salvage RP in terms of reduced morbidity. Patients with local recurrence after radiation therapy are at increased risk of metastatic progression and cancer-specific mortality. Currently, salvage RP represents the only curative treatment option for these patients. Salvage RP may favorably alter the natural history of biochemical recurrence after radiation therapy, but it must be instituted early in the course of recurrent disease to be effective.
