Interleukin 6 and cancer treatment.

Interleukin 6 (IL-6) is a pleiotropic cytokine, with a wide range of biological effects. The diverse biological actions of IL-6 could play important roles in the enhancement or suppression of tumor growth and development. IL-6 has been seen to act as an autocrine and/or paracrine growth factor for various human tumors, including multiple myeloma, renal cancer, and AIDS-associated Kaposi's sarcoma. However, IL-6 also can exert potent anti-tumor effects: administration of IL-6 has been seen to result in decreased tumor appearance in experimental animal systems. Therefore, potentially useful anti-tumor therapeutic strategies could include the inhibition of the activity of IL-6, or alternatively, the enhancement of anti-tumor responses by the administration of exogenous IL-6.

Augmentation of cytotoxicity of lymphokine activated killer cells on ovarian tumor cells by various biological response modifiers.

The effect of combining lymphokine activated killer (LAK) cells with either recombinant interleukin-2 (rlL-2), recombinant interferon-alpha (rIFN-alpha), recombinant tumor necrosis factor (rTNF) or streptococcal preparation OK-432 were assessed, using Raji, 2 kinds of cultured ovarian lines (PA-1 and SKOV-3), and 7 fresh ovarian tumor lines. LAK cells were generated by culturing peripheral blood lymphocytes (PBL) with rIL-2 for 3-5 days. The simultaneous combination of LAK cells with rIFN alpha or OK-432 augmented the cytotoxicity of LAK cells. The susceptibility of tumor cells to LAK cells also increased after the pretreatment of tumor cells with OK-432. These results suggest that the simultaneous injection of LAK cells with rIFN-alpha or OK-432 and the intralesional injection of OK-432 prior to the adoptive transfer of LAK cells may be a beneficial combination treatment for LAK treatment.

Uterine corpus and cervical cancer.

Cancers of the cervix and uterus occur in approximately 50,000 women each year in the United States. As a group, these cancers represent our sixth most common cancer overall, are second only to breast cancer, and are roughly equal to the lung cancer incidence in women. Although they comprise 11% of all cancers in females, they represent only 4% of cancer deaths in women. This results from the effective application of surgery and radiation therapy in the management of these two malignancies as well as effective techniques for early diagnosis. The overall death rate from these two malignancies has decreased more than 70% in the last 40 years. Successful outcome rests on both early diagnosis and the careful application of established treatment approaches. This monograph summarizes the management approaches to both uterine corpus and cervical cancer and discusses the role of adjuvant therapy for these major malignancies. Detailed presentations of the management of special problems, including the uterine sarcomas, are also presented. Although standard management approaches are detailed, discussion of experimental approaches, including adjuvant hormonal treatment, single agent and combination chemotherapy, and the use of radiation sensitizers is included.
