ABSTRACT Mycobacterium bovis bacillus Calmette-Guérin (BCG) has become the predominant conservative treatment for nonmuscle invasive bladder cancer. Its mechanism of action continues to be defined but has been shown to involve a T helper type 1 (Th1) immunomodulatory response. While BCG treatment is the current standard of care, a significant proportion of patients fails or do not tolerate treatment. Therefore, many efforts have been made to identify other intravesical and immunomodulating therapeutics to use alone or in conjunction with BCG. This paper reviews the progress of basic science and clinical experience with several immunotherapeutic agents including IFN-α, IL-2, IL-12, and IL-10.

    ABSTRACT: Primary lung adenoid cystic carcinoma (ACC) is extremely rare and accounts for approximately 0.1%-0.2% of all lung cancers. ACC of the head and neck has generally been regarded as a slow-growing, low-grade malignancy which has a tendency for local recurrence and frequent distant metastasis. When ACC of the lung is identified, physicians must determine whether it represents distant metastasis or a primary lung cancer. Thyroid transcription factor-1 staining is one of the most useful methods to differentiate primary from metastatic lesions in lung cancer. Herein we report a case of metachronous, not synchronous, ACC at the peripheral lung followed by ACC presentation at the base of the tongue, and review of relevant literatures.

    ABSTRACT: The most effective intravesical treatment of non-muscle-invasive bladder cancer is instillation of live Mycobacterium bovis bacillus Calmette-Guérin (BCG). BCG stimulates the release of cytokines, contributing directly or indirectly to its effectiveness. However, the function of specific cytokines is not well understood. We have undertaken a nonsystematic review of primary evidence regarding cytokine detection, activation and response in BCG patients. Cytokines IL-2, IL-8 and TNF-α appear to be essential for effective BCG therapy and nonrecurrence, while IL-10 may have an inhibitory effect on BCG responses. IL-2, IL-8, TRAIL and TNF-α are potentially predictive of response to BCG. Alterations in genes encoding cytokines may also affect responses. There are significant data showing the association of certain cytokines with successful BCG treatment, and which may be useful predictive markers. Isolating those cytokines mediating efficacy may hold the key to ameliorating BCG's side effects and improving efficacy and patient compliance.

    ABSTRACT: The aim of this study was to evaluate the antitumor immune response of the Bacillus Calmette-Guérin (BCG) in an orthotopic bladder cancer model. The murine bladder cancer cell line MBT-2 was transurethrally implanted in the bladder of syngeneic female C3H/He mice. The animals were randomly divided into three treatment groups: Phosphate-buffered saline (PBS), low-dose BCG and high-dose BCG. The analyses of luciferin-stained tumor images 28 days after each treatment showed significant tumor growth inhibition in the high-dose group in comparison with that in the low-dose- or PBS-treated groups. In addition, the percentage of myeloid-derived suppressor cells in the high-dose group was significantly suppressed in comparison with that in the PBS and low-dose agent treatment groups. These findings are notable in terms of the clinical evaluations of this therapy for patients with bladder cancer. The outcomes of this study also provide important implications regarding antitumor immune responses in human cancer.
