[Clinical analysis of 59 cases of primary gastric non-Hodgkin's lymphoma].
Bibliographic record
Abstract
BACKGROUND & OBJECTIVE: Gastrointestinal tract is the most common extranodal involvement site of non-Hodgkin's lymphoma (NHL). However, no standard treatment regimen has ever been established for primary gastric NHL (PGNHL). This paper was to summarize the clinical characteristics and treatment results of PGNHL patients. METHODS: Records of 59 PGNHL patients, treated from Jan. 1980 to Jan. 2002 in Cancer Center of Sun Yat-sen University, were reviewed to summarize their clinical characteristics, and influence of treatment modality on their survival. RESULTS: Of the 59 PGNHL patients, 46 (78.0%) were in stage I/II. According to Working Formulation, most of them were in intermediate grade (46, 78.0%). The most common immune phenotype was B-cell lineage (46/49, 93.9%). These patients were treated with chemotherapy plus surgery (37,62.7%), chemotherapy alone (17,28.8%), and surgery alone (5,8.5%), respectively. The 2-, 5-, and 10-year survival rates of the 59 patients were 76.4%,63.7%, and 42.5%, respectively. For those patients in intermediate grade (including immunoblastic cell lymphoma), there was no significant difference in the 5-year survival rate between the patients received chemotherapy plus surgery and the patients received chemotherapy alone (52.5% vs. 57.1%). CONCLUSIONS: Chemotherapy-dominated modality is recommended for patients with PGNHL of intermediate or high grade. The effect of surgery on PGNHL needs to be confirmed by prospective randomized trial.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
