A 37-year-old patient with liver metastases from gastric cancer was treated with a double adoptive immunotherapy regimen comprising tumor-infiltrating lymphocytes plus interleukin-2 and subsequently local-regional lymphokine-activated killer cells plus interleukin-2 because of an extremely high in vitro cytotoxic specific activity on established gastric cancer cell lines. The necrosis verified in the center of the hepatic metastasis would appear to demonstrate treatment efficacy, but no clinical response was seen. In vitro cytotoxicity data alone are insufficient to predict the clinical efficacy of adoptive immunotherapy.

PURPOSE Adoptive immunotherapy with tumor-infiltrating lymphocytes (TIL) and interleukin-2 (IL-2) has been reported to mediate tumor regression in some human cancers. To define better the biologic characteristics of TIL, especially survival and distribution in vivo, we performed a gene-marker study in patients with advanced malignancies. PATIENTS AND METHODS We treated five patients with metastatic melanoma or renal cell carcinoma with adoptive immunotherapy. TIL were genetically modified, before their infusion, using a recombinant retroviral vector that contained the marker gene coding for resistance to neomycin (NeoR). RESULTS All of the patients tolerated the treatment well and none of the theoretic safety hazards due to the retroviral gene transduction was observed. The presence of the NeoR gene in TIL was detected by Southern blot analysis, with an efficiency of transduction that ranged from 1% to 26%. With polymerase chain reaction (PCR) analysis, we demonstrated that gene-modified TIL can survive for several months after reinjection, since positive blood samples were observed up to day 260 following reinjection. Eight malignant biopsy specimens were obtained from three patients after cell infusion. TIL were detected in only four of these eight tumor deposits on days 7 and 260. CONCLUSION These results confirm the feasibility and safety of using in vitro retroviral gene transduction in human lymphocytes to analyze their in vivo distribution for further therapeutic applications. However, a selective and prolonged retention of TIL at the tumor site was not found in this study.

Clinical investigations using the adoptive transfer of lymphokine-activated killer (LAK) cells and recombinant interleukin-2 (rIL-2) to treat patients with advanced cancer have yielded encouraging results. We have thus sought ways to enhance the effectiveness of adoptive immunotherapy while minimizing its toxic side effects. Murine experiments have identified tumor-infiltrating lymphocytes (TIL) as killer cells more effective than LAK cells and less dependent on adjunctive systemically administered IL-2 to mediate antitumor effects. Accordingly, we performed a pilot protocol to investigate the feasibility and practicality of administering IL-2-expanded TIL to humans with metastatic cancers. Twelve patients, including six with melanoma, four with renal cell carcinoma, one with breast carcinoma, and one with colon carcinoma, were treated with varying doses and combinations of TIL (8.0 X 10(9) to 2.3 X 10(11) cells per patient), IL-2 (10,000 to 100,000 U/kg three times daily to dose-limiting toxicity), and cyclophosphamide (CPM) (up to 50 mg/kg). Two partial responses (PR) to therapy were observed: pulmonary and mediastinal masses regressed in a patient with melanoma, and a lymph node mass regressed in a patient with renal cell carcinoma. One additional patient with breast cancer experienced a partial regression of disease in lymph nodal and cutaneous sites with complete elimination of malignant cells from a pleural effusion, although cutaneous disease recurred at 4 weeks. The toxicities of therapy were similar to those ascribed to IL-2; no toxic effects were directly attributable to TIL infusions. In five of six melanoma patients, TIL demonstrated lytic activity specific for the autologous tumor target in short-term chromium-release assays, distinct from the nonspecific lytic activity characteristic of LAK cells. This study represents an initial attempt to identify and use lymphocyte subsets with enhanced tumoricidal capacity in the adoptive immunotherapy of human malignancies.

✓ Methods have recently been described for the isolation and expansion of lymphocytes that have trafficked into animal and human tumors. These CD8-positive tumor-infiltrating lymphocytes (TIL's) have exceptional trafficking ability to, and efficacy against, tumor targets in extracranial sites. Prior to Phase I clinical trials for patients with gliomas, adoptive immunotherapy with TIL's was studied in a mouse model of primary brain tumors to determine if intracerebral tumors have a similar response. Glioma 261 (GL261) tumors were grown in the subcutaneous space of C57BL/6 mice. After enzymatic digestion, the cells were incubated in vitro with interleukin-2 (IL-2) until a confluent population of T lymphocytes was present. The in vitro efficacy of these TIL's was tested against fresh GL261 targets with a chromium release assay; the in vivo efficacy was tested against GL261 tumors in the liver and against irradiated and nonirradiated GL261 tumors in the brain. Mice received one of the following: intraperitoneal saline; intraperitoneal IL-2 (7500 to 50,000 U three times daily for 5 days); IL-2 plus intravenous TIL's (1 to 3 × 107 cells); 10 Gy cranial irradiation; irradiation plus IL-2; or irradiation plus IL-2 plus TIL's. The TIL preparation killed 77% of tumor targets in 4 hours at an effector:target ratio of 100:1. In animals with GL261 tumors in the liver, at 2 weeks there were 93 ± 37, 128 ± 45, and 21 ± 14 liver metastases in the control, IL-2, and IL-2 plus TIL groups, respectively. However, in animals with GL261 tumors in the brain, no treatment group had an increased survival rate compared to the control group. It is concluded that, although TIL and IL-2 immunotherapy can be used effectively to treat brain tumors in vitro and at sites outside the central nervous system, it is ineffective against the same type of tumor in the brain. Different methods of delivery or different combinations of these immunomodulators may be more effective; however, based on these findings, treatment of patients with IL-2 and TIL cannot be recommended until efficacy has been demonstrated in an animal model.
