Abstract
Purpose: This case report describes a patient with vitreoretinal lymphoma who subacutely developed a large, peripapillary subretinal infiltrate that rapidly and spontaneously resolved. Methods: A case report is presented. Results: A 65-year-old Asian-American woman was referred for evaluation of a dense, peripapillary subretinal infiltrate in the left eye. A diagnostic vitrectomy revealed large, atypical lymphocytes with irregularly shaped nuclei, and mutational testing was positive for myeloid differentiation primary response 88 ( MYD88). Prior to surgery, the patient’s subretinal infiltrate had begun to resolve spontaneously, a process that continued after surgery without initiation of systemic or local ocular therapy. Conclusions: Patients with vitreoretinal lymphoma may present with transient, subretinal infiltrates that can resolve without treatment.

Abstract
Background Spontaneous remission in solid malignancies has been documented. However, spontaneous remission in aggressive diffuse large b cell lymphoma is exceedingly rare. Previous reports of lymphoma remission suggest that not yet fully characterized tumor-intrinsic and microenvironment mechanisms cooperate with spontaneous regression. Case description Here, we report the case of an 88-year-old white woman with diffuse large b cell lymphoma (follicular lymphoma transformed) who achieved morphologic spontaneous remission 3 months after her diagnostic core biopsy. We examined 16 similar cases of diffuse large b cell lymphoma suggesting that spontaneous remission is preferentially observed in elderly patients soon after their biopsy microtrauma, especially if malignancies are Epstein–Barr virus driven and activated B-cell type. Conclusion Our case and reported analysis highlight that anti-tumor adaptive T cell responses are potentially augmented in a subset of patients leading to lymphoma regression. In these patients, it is possible that “primed” innate anti-tumor T cell immunity is enhanced in immunogenic lymphoma subtypes after tissue biopsy. Our case and analysis not only reinforce the role of innate T cell anticancer immunity, but also originates potential proof of concept for investigation of unexplored pathways that could favorably impact T cell therapy.

Abstract
Spontaneous tumour regression after high‐dose therapy and autologous stem cell transplantation is associated with the aplastic anaemia‐like syndrome and the presence of polyclonal autoantibodies against carbonic anhydrase I (CA I). When tumour cells were grown in vitro in the presence of patients’ sera positive for anti‐CA I autoantibodies, their morphological pattern was altered. These changes were accompanied by modifications in the gene expression profile. We observed downregulation of genes of the basal lamina assembly (collagen type IV alpha 4, the laminin subunit gamma 2), the extracellular matrix (collagen type I alpha 1), the cytoskeleton (keratin 14 type I), the collagen triple helix repeat containing 1 and the proto‐oncogene WNT7B. On the other hand, the expression of the CA 1 gene was increased in the tumour cells. It was also noticed that the presence of anti‐CA I autoantibodies did not impair tumour cell proliferation and cell viability in vitro. These findings were observed only in the presence of patients’ sera positive for anti‐CA I autoantibodies.

Abstract
Complete regression of high-grade lymphoma is extremely rare. We report 1 such case that might have been conceivably mediated by Ganoderma lucidum (Lingzhi), an immunomodulatory herbal medicine. A 47-year-old man presented with epigastric pain. Endoscopy revealed a large gastric ulcer, which on biopsy was diagnostic of large B-cell lymphoma. At gastrectomy 11 days later, no evidence was found of large B-cell lymphoma despite thorough sampling. Instead, there was a dense and permeative infiltrate of CD3+ CD8+ cytotoxic small T lymphocytes spanning the whole thickness of the gastric wall. In situ reverse transcription polymerase chain reaction for T-cell receptor β-chain family did not detect a monoclonal T-cell population. We postulate that the cytotoxic T cells may represent an active host−immune response against the large B-cell lymphoma that resulted in a complete regression. On questioning, the patient had taken megadoses of Ganoderma lucidum, which might have triggered the successful immune reaction.

Abstract
We present the first reported case of lung large cell neuroendocrine carcinoma (LCNEC) with spontaneous regression followed by progression. An 85-year-old woman presented with a 2.8-cm nodule in the right upper lung lobe on chest computed tomography. After four months, the tumor decreased to 1.8 cm and remained unchanged in size for the next three months, but it grew to 8.6 cm and invaded the mediastinal fat tissue after approximately one year. Ultrasound echo-guided percutaneous biopsy revealed the tumor to be LCNEC. The patient underwent a right upper lobectomy with lymph node dissection. She had a good postoperative course with no complications. Physicians and surgeons should be aware that radiographic regression of a pulmonary nodule does not necessarily exclude the possibility of lung cancer.

Abstract
Spontaneous regression of malignancies is a very rare phenomenon. Our research of existing literature yielded only 16 cases of Hodgkin's lymphoma which regressed spontaneously. The outcome of primary progressive Hodgkin's lymphoma is poor even with salvage chemotherapy and autologous bone marrow transplantation. Here we present a case of primary progressive Hodgkin's lymphoma, which regressed spontaneously after failure of salvage chemotherapy. To our knowledge, this is the first case report of primary progressive Hodgkin's lymphoma undergoing spontaneous regression.

Abstract
We report two cases of human herpesvirus-8 (HHV-8)-negative large B-cell lymphoma involving pericardial and/or pleural effusion that regressed after drainage alone. Case 1 is a 70-year-old man showing massive pericardial effusion. Cytology of the drained effusion showed monotonous infiltration of CD3-, CD20+, CD79a+, and CD138- large B-cells. Monoclonality was shown by Southern blot analysis. Case 2 is a 70-year-old man with massive pericardial and bilateral pleural effusion. Cytology of pericardial effusion showed infiltration of CD20+, CD45RO-, CD138-, immunoglobulin lambda chain+, and kappa chain- large B cells. In both cases, effusion resolved after drainage and no relapse has been observed. HHV-8 was not demonstrated in either case. Clinical presentation of our two cases resembled primary effusion lymphoma (PEL), but cytomorphology, immunophenotype, and prognosis were clearly distinct from those of PEL. HHV-8-negative effusion lymphomas might include prognostically favorable self-limited tumors that could regress without any cytotoxic therapy.

Abstract
Solitary plasmocytoma is a rare tumour that belongs to the myeloid dysplasia group. The authors present an unusual evolution of this pathology through a clinical case. A 42-year-old patient was diagnosed with solitary nasosinusal plasmocytoma following biopsy of the right nasal fossa process; several weeks after this the tumour spontaneously regressed. Extramedullar plasmocytoma is a myeloid dysplasia that seldom evolves into multiple myeloma. Spontaneous regression has been described for some malignancies, implying immunological factors, but not previously for extramedullary plasmocytoma.

Abstract
Engineered antibodies have become an invaluable source of biopharmaceuticals against a wide range of diseases. About 200 antibody-based biologicals have been tested in clinical trials. Single chain variable fragments of antibodies (scFvs) provide binding specificity and offer an increased ease of in vitro display selection. Here, we present the generation of a human scFv library from peripheral blood lymphocyte RNA of a patient with relapsed T-cell non-Hodgkin lymphoma (T-NHL) who experienced a rare case of "spontaneous" remission. Antibodies against human T-cell antigen CD28, a co-stimulatory protein that influences the immune response by amplification of the transcriptional effects of T-cell receptors, might have contributed to the patient's remission. The scFv library was panned against CD28 using ribosome display and further subjected to affinity maturation. Isolated scFv were assessed for binding specificity and affinity and may provide the basis for the development of novel immunotherapeutic strategies. This work demonstrates the selection of a fully human antibody fragment from a patient-derived gene pool by in vitro ribosome display technology.

Abstract
Advanced Hodgkin's disease is usually treated with six or more cycles of combination chemotherapy. Spontaneous regression of the cancer is very rarely reported in patients with Hodgkin's disease. We present an unusual case of a patient with Hodgkin's disease who experienced complete remission with a single cycle of chemotherapy, followed by pneumonia. The case was a 36-year-old man diagnosed with stage IVB mixed cellularity Hodgkin's disease in November 2000. After treatment with one cycle of COPP-ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine) chemotherapy without bleomycin, the patient developed interstitial pneumonia and was cared in the intensive care unit (ICU) for two months. Follow-up chest computerized tomography (CT), performed during the course of ICU care, revealed markedly improved mediastinal lymphomatous lesions. Furthermore, follow-up whole body CT and 18-fluorodeoxyglucose positron emission tomography showed complete disappearance of the lymphomatous lesions. Four years later, the patient is well and without relapse. This report is followed by a short review of the literature on spontaneous regression of Hodgkin's disease. To the best of our knowledge, this is the first case report of spontaneous remission of Hodgkin's disease in Korea.

Abstract
A complete spontaneous regression of diffuse large B cell lymphoma involving the right breast, confirmed by aspiration cytology, is reported. The patient visited a hospital due to the rapid growth of a tumor in the right breast. Five years previously she underwent a craniotomy for a brain tumor, diagnosed as B-cell malignant lymphoma, and received several courses of irradiation to the brain. Analysis of the breast tumor cells obtained by aspiration revealed lymphoma cells morphologically, which were similar to the tumor cells in the brain expressing CD20. While waiting for further examination, the tumor regressed rapidly and was not palpable after 20 days. An excisional biopsy of the breast exhibited no definite malignant lymphoma cells among a diffuse population of CD45RO and CD8-positive small lymphocytes. Nucleotide sequencing of HCDR3s of the brain tumor and breast tumor cells showed a completely matched sequence, revealing the breast mass to be a metastatic lesion from the tumor of the brain. Although there was no tumorous lesion, the patient received additional chemotherapy and has shown no sign of recurrence in the breast for 7 years. We were able to confirm that the breast lymphoma shown in the aspiration cytology was a metastatic one, which was not proven histologically prior to chemotherapy, and regard the present case as a malignant lymphoma of the breast showing spontaneous regression. The present case shows a rare occurrence of spontaneous regression of diffuse large B cell malignant lymphoma after aspiration and suggests that CD8-positive T cells might be related to the regression.

Abstract
BACKGROUND Natural killer (NK) cells are critical in resistance to B16F10 lung metastases in B6C3F1 mice. Activation of NK cells by polyinosinic:polycytidylic acid (poly I:C; 0.1 mg, intraperitoneally) increases resistance to B16F10 cells. This effect is reduced after administration of ethanol (EtOH; 6 g/kg by oral gavage). The present study was conducted to determine whether decreased resistance is due to alteration of the distribution and/or the activation of NK cells. METHODS These parameters were measured in the spleen, lungs, and peripheral blood 4 and 12 hr after EtOH and poly I:C administration. For assessing the time after poly I:C administration during which NK cells are important in resistance to B16F10 cells, anti-NK1.1 antibody was used to deplete NK cells in vivo 48 hr before and 0, 6, 12, and 24 hr after intravenous injection of B16F10 tumor cells. RESULTS Depletion of NK cells at any time up to 12 hr after B16F10 administration significantly increased the number of tumor nodules in the lungs, but depletion at 24 hr had a smaller effect. Flow cytometry revealed that there was a small but significant increase in the percentage of NK cells in the lungs at 12 hr, which was not changed by EtOH. Corresponding NK cell lytic function in the lungs was increased significantly at both 4 and 12 hr by poly I:C. However, the increase was not significantly different from the naive control value at 4 hr in mice treated with poly I:C plus EtOH, indicating that EtOH decreased activation of NK cells in the lungs at 4 hr. In the spleen, no treatment significantly altered the percentage of NK cells at 4 or 12 hr. However, poly I:C significantly enhanced lytic function, and this enhancement was suppressed by EtOH (by approximately 50%). In the blood, the only significant change in NK cell percentage or lytic activity was an increase in the percentage of NK cells at 12 hr, which was equivalent in the poly I:C and the poly I:C plus EtOH groups. CONCLUSIONS These results demonstrate that EtOH partially abrogates the poly I:C-induced enhancement of resistance to B16F10 cells and that decreased activation of NK cells in the lungs at a critical time early in the response to poly I:C may contribute to this effect. Other parameters could also contribute, but there was little support for an important role for changes in NK cell distribution.

Abstract
Primary central nervous system lymphoma (PCNSL) is a relatively uncommon disease in which spontaneous remission is exceedingly rare. We are reporting three cases of primary CNS lymphoma with spontaneous regression in two to eight weeks, from the time of the initial diagnosis. The remission lasted for four years in the first case, two years in the second, and one year in the third case. Tissue diagnosis was made in the first two cases after relapse, and in the third case a biopsy was done at the initial presentation. The literature and the possible pathophysiological mechanisms of this interesting phenomenon are discussed.

Abstract
Using a newly described analysis of natural killing activity employing an "individual effector/target cell ratio" according to the number of effector cells in blood, we recently determined that patients with spontaneous lymphoma regression had elevated natural killing activity prior to regression. To clarify the clinical significance of natural killing activity in patients with advanced lymphoma, a prospective study was performed at a single institution in 43 untreated patients. Survival was analyzed to detect prognostic variables. Among factors chosen initially by univariate analyses, multivariate analysis selected three prognostic factors: chemotherapy response (P < 0.0001), low-grade lymphoma (P = 0.0005), and natural killing activity (P = 0.0052). Within the chemotherapy response, natural killing activity was a unique correlative factor (P < 0.0001) selected by a multivariate regression analysis using forward selection method. In patients with advanced lymphoma, natural killing activity is a valuable prognostic factor and may also predict the response to chemotherapy.
