Two patients developed
non-Hodgkin's lymphoma
(
NHL
) six and ten years after radiotherapy and chemotherapy for Hodgkin's disease nodular sclerosis type. The histological classification of the developing
NHL
for the two patients was: IgG (K) secreting lymphoplasmacytoid lymphoma of the stomach, and immunoblastic lymphoma of the cervical lymph nodes. Both patients responded well to conventional chemotherapy for
NHL
and are alive 22 and 5 months after the diagnosis of the
secondary tumor
. Forty eight cases of
NHL
after treatment for HD have been previously reported. We present a review of the literature of these cases, adding to this literature the first reported case of gastric lymphoplasmacytoid lymphoma under such circumstances.

The association of radiotherapy (RT) and chemotherapy (CT) constitutes one of the main avenues for research in therapeutic oncology. This association has two aims: (1) increase in control rate of primary tumor (this requires either the potentiation of one of the two modalities by the other or the additivity of their effect on tumor cells without a parallel increase in the toxic effects on critical normal tissues); (2) spatial cooperation (RT being used for the control of the primary tumor or of the sanctuaries, and CT for the control of the disseminated disease). In these two strategies, RT and CT should be given up to full doses in order to be effective. The main risk is an increase in the number and severity of the early and late side effects. To circumvent this problem, two possibilities are being explored: (1) use of drugs without serious toxic effects on those critical tissues which are included in the irradiated volume; and (2) avoidance of concomitant administration and introduction of a sufficiently long-time gap between the completion of one modality and initiation of the other. However, in such sequential treatment, a delay of CT until after the completion of RT, or an interruption of CT cycle during the course of RT, allows the occult
metastases
to increase in size; a similar delay in initiation of RT is also detrimental, as drugs are often not effective on bulky tumors. Moreover, under CT, the cells which are resistant to the cytotoxic drugs may disseminate and initiate chemoresistant
metastases
. Taking these disadvantages into account, a treatment protocol was proposed in 1980 in which CT and RT are given alternately, without undue delay. Chemotherapy is started with the usual scheduling of one cycle every month. Radiotherapy courses are interdigitated between CT cycles. Each course is initiated 1 week after interrupting CT and continued until 1 week before beginning the subsequent cycle of chemotherapy, and so on until completion of RT. Such split-course RT should have an effect on a tumor comparable to that of a conventional fractionation. This protocol has been used on 24 patients with
non-Hodgkin's lymphoma
(
NHL
) of diffuse histology, and 63 patients with small cell carcinoma of the lung. The 2-year relapse-free survivals are promising (in clinical stage II
NHL
of diffuse histology, 75%; and in small cell lung carcinomas, 33%).(ABSTRACT TRUNCATED AT 400 WORDS)

IgA antibodies to Epstein-Barr virus capsid antigen (IgA anti-VCA) can be detected in sera of patients with certain types of nasopharyngeal carcinoma (NPC). IgA anti-VCA titres were determined by the indirect immunofluorescence technique. 17 control patients with benign diseases or carcinomas of the head and neck other than NPC had negative IgA anti-VCA titres less than or equal to 1:16. NPC was diagnosed histologically according to the Cologne modification of the WHO classification. Among 16 cases of untreated or recurrent NPC, a rare disease in Europe, seen over the past three years, those with undifferentiated carcinomas with and without lymphoid stroma and the non-keratinizing carcinomas with lymphoid stroma were IgA anti-VCA positive (1:32 to 1:512), whereas patients with squamous cell carcinomas were negative. In four cases the primary tumour had not been diagnosed by other ENT doctors in spite of known regional or distant
metastases
consisting of undifferentiated carcinomas with or without lymphoid stroma. IgA anti-VCA antibodies in the sera of these patients indicated the probable site of the primary tumour. NPC was verified by biopsy in all these cases. In 2 serologically negative patients the original diagnosis of undifferentiated NPC with lymphoid stroma had to be revised to malignant
Non-Hodgkin lymphoma
. In the follow-up of 6 NPC patients the trend of changes in IgA anti-VCA titres correlated with the course of the disease, but the minute tumour-related changes could be detected only when at least two previous sera of the same patient were included in every test.(ABSTRACT TRUNCATED AT 250 WORDS)

99 cases of undifferentiated carcinomas of the thyroid and nine cases of primary malignant Non-Hodgkin lymphomas of the thyroid were examined from 1967 to 1983 in our institute. Among the undifferentiated carcinomas nine cases were classified as small cell subtype. Over the years, the histopathological handling in regard to small cell subtype of undifferentiated carcinoma and primary malignant
Non-Hodgkin lymphoma
has changed. The frequency of primary malignant
Non-Hodgkin lymphoma
has increased conspicuously in the last few years, whereas the number of small cell carcinomas decreased. A reclassification, based on immunohistochemical investigation for tumor markers of the nine cases originally diagnosed as small cell carcinomas from 1967 to 1983 revealed that five cases were poorly differentiated carcinomas or undifferentiated carcinomas of the spindle cell type. In three cases the primary diagnosis had to be revised into malignant
Non-Hodgkin lymphoma
of the diffuse "histiocytic" type. The postmortem examination of the patient with the remaining small cell carcinoma "of the thyroid" revealed a clinically undetected small cell carcinoma of the lung with
metastases
to the cervical lymph nodes and the thyroid gland. These findings are in agreement with the results of several recently published papers indicating that true small cell carcinoma of the thyroid must be a very rare tumor.

The authors describe autopsy cases of primary extranodal
non-Hodgkin's lymphoma
of the oral regions in 11 (8%) of 134 patients: 10 were clinical stage IE, and one was IIE. Histologic subtypes of each lymphoma included the diffuse large cell type (8 cases), diffuse mixed type (2 cases) and Burkitt's type (1 case) according to the Japanese Lymphoma Study Group (JLSG) classification. All patients received anti-lymphomatous chemotherapy and/or radiotherapy. Nine cases had active disease, 3/9 manifesting leukemia. Nodes were involved. There was involvement of cervical lymph nodes in 7 (64%). Viscera most commonly involved were, in order of decreasing frequency: lung, kidney, pancreas, liver, spleen, heart, gastrointestinal tract, bone marrow, and adrenal gland. It is apparent that primary extranodal non-Hodgkin's lymphomas of the oral region arise in a single focus, and extensions of the disease are not random. The primary lesions spread to regional lymph nodes by way of lymphatic channels, and to extranodal organs of the intrathoracic and intraabdominal regions by contiguous direct invasion of adjacent organs and by blood-borne
metastases
. Wide spread dissemination at the time of death was found in 6 cases and 3 modes of spreading were observed.

Between 1975 and 1986, the Manchester Lymphoma Group treated 127 patients with localized (Stages I/II) high and intermediate grade
non-Hodgkin's lymphoma
(
NHL
) on one of three protocols of combined involved field radiotherapy and chemotherapy. The study included patients with widespread bulky abdominal disease providing there was no apparent spread outside the abdomen and the liver was not involved with
metastatic disease
. The median duration of follow-up was 70 months. The complete response rate was 86% and the overall 5-year survival was 70%. The 5-year relapse-free survival of the complete responders was 80%. Cox model multivariate analysis showed that bulk disease (greater than 5 cm), low serum albumin and gut involvement were the pretreatment factors associated with shorter survival. When remission status was included in the model the attainment of a complete response was the major determinant of long-term survival but bulk disease and gut involvement were still significant adverse predictors for survival. These factors need to be assessed when analysing results of therapy in
NHL
and in the design of future treatment strategies.

A monoclonal antibody, NKI/beteb, was prepared against membranes from a human melanoma metastasis, and in immunoprecipitates of melanoma cell lysates specific 100- and 7-kd glycoproteins were found. The large glycoproteins were also present in conditioned medium of melanoma cell lines. The antigen is located on the inner side of membranes of (pre)melanosomes and premelanosomelike vesicles. The antibody reacted in the immunoperoxidase test on frozen tissue sections with 27 of 28 nevocellular nevi (15/16 common, 12/12 dysplastic), 39/39 primary melanomas (3 intraepidermal, 24 cutaneous, 12 choroidal), 56/63 melanoma
metastases
, and 4/4 clear-cell sarcomas (melanoma of soft tissue). With sections of formalin-fixed paraffin-embedded tissues, the reaction was less sensitive. No reactivity was detected with frozen sections of 185 other tumors, except for 1 case of
non-Hodgkin's lymphoma
in which macrophages were positive. With the exception of melanocytes, all frozen sections of adult tissues that were tested were negative with NKI/beteb. On the basis of its tissue distribution so far, the antigen recognized by NKI/beteb seems to be a specific and sensitive diagnostic marker for cells of the melanocyte lineage.

The histological diagnosis of
non-Hodgkin's lymphoma
(Burkitt's lymphoma excluded) in 147 children was reviewed. The most common site of presentation was in the abdomen (32.6%). The most frequent site of
metastatic disease
at diagnosis was the bone marrow (27.2%). The most common histology was diffuse undifferentiated non-Burkitt type (37.4%). According to the Murphy staging system, 40.1% were stage III and 27.2% were stage IV. In a nonrandomized prospective study, 121 patients were submitted to a treatment regimen (protocol 8001) and compared with 26 historical controls treated with the COP regimen, consisting of cyclophosphamide, vincristine, and prednisone. Of those patients treated with protocol 8001, nine had intestinal perforation at the site of primary disease. All patients in this group were malnourished at the time of perforation. The overall rate of initial complete remission in those patients treated with protocol 8001 was 90.7%. The duration of remission was from 16 to 108 months, with a median of 39 months. The actuarial rate of disease-free survival was 69% at 2 years and 63% at 6 years, compared with 36% at 6 years of the control group (COP) (p less than 0.01). None of the patients have relapsed after 4 years.

Eleven population-based cancer registries tabulated second cancers among 133,411 patients diagnosed with testicular cancer, ovarian cancer or Hodgkin's disease between 1945 and 1984. Overall, 3,157 second cancers were observed, as compared with 2,420 expected at least one year after the first cancer. Survivors of testicular and ovarian cancer experienced 30% and 20% more cancers respectively than the general population comparison group, and patients previously diagnosed with Hodgkin's disease had an 80% excess of cancer. No information was available either on treatment for the first cancer, or other risk factors. However, temporal patterns in the risk of specific second cancers were analysed, with particular reference to the possible role of therapy for the first cancer. Leukaemia of the acute or non-lymphatic type, which has been previously linked to alkylating agent therapy, occurred in excess following all 3 first cancers, as did
non-Hodgkin's lymphoma
(overall relative risks of 6.1 and 1.8 respectively, with considerably higher relative risks following Hodgkin's disease). Other cancers for which important and plausibly therapy-induced excesses occurred were lung cancer following Hodgkin's disease (relative risk 1.9), breast cancer following Hodgkin's disease (relative risk 1.4) and bladder cancer following ovarian cancer and Hodgkin's disease (relative risks 1.7 and 2.2 in women, respectively). Rarer sites at which striking excesses occurred were the salivary gland, thyroid, bone and connective tissue. There were smaller, but clear excesses for cancers of the rectum and colon following ovarian cancer and testicular cancer, skin cancer following Hodgkin's disease, and kidney cancer following ovarian cancer. Overdiagnosis, misclassification of
metastases
and confounding by other risk factors were all considered as explanations of observed excesses. Nonetheless, it appeared that there are clear excess risks for cancers other than acute leukaemia which must be ascribed to therapy for the first cancer, especially in view of the possible under-reporting in registry material. Case-control studies are under way to provide information on the role of specific aspects of therapy.

Sixty-two cases of orbital and periorbital palpable neoplasms were analyzed cytologically. The material was obtained by our technique of simply introducing a fine injection needle in the tumor mass without aspiration. Fifty-six of these tumors had a subsequent histologic diagnosis by surgical procedure or biopsy. Forty-nine of the 56 cytologic diagnoses (87%) were concordant with the histologic findings with regard to malignancy and its variety. In three other cases the diagnosis of malignancy was only achieved by surgical procedure or biopsy (5%). In two cases, there were false-malignant results (4%), one corresponding to a meningioma and the other related to a reactive lymphoid hyperplasia. There was one false-benign (2%) result in a case of
non-Hodgkin's lymphoma
. In one patient, the cytologic material was insufficient for diagnosis (2%). In six other cases, the initial cytologic examination was ultimately confirmed either by biochemical studies or by biopsies of nodal
metastases
. No orbital hemorrhage was observed after fine-needle sampling. This outpatient technique is highly accurate and permits diagnosis in a few minutes.
