ABSTRACT This study was conducted to determine the incidence and clinical characteristics of lacrimal drainage obstruction (LDO) in patients receiving S-1 chemotherapy.
Consecutive 170 patients with gastric cancer who underwent curative surgery and received adjuvant S-1 chemotherapy were enrolled. S-1 was administered orally (40 mg/m2 b.i.d. on days 1-28 every 6 weeks) for 1 year. Ophthalmologic examinations were carried out on patients complaining of epiphora.
Thirty-one patients (18%) developed epiphora. Among 31 patients, 25 underwent ophthalmologic examinations and 22 (88%) were diagnosed with LDO. The median time to the onset of LDO was 2.9 months. The most common site of obstruction was the nasolacrimal duct [86% (19/22)]; punctal [23% (5/22)] and canalicular obstruction [14% (3/22)] were also noted. In multivariate analysis, total gastrectomy [versus partial gastrectomy: hazard ratio (HR), 2.9; P=0.014] and creatinine clearance<50 ml/min (versus ≥50 ml/min: HR, 2.9; P=0.038) were independent risk factors for the development of LDO.
Considering the high incidence of LDO in patients receiving S-1 chemotherapy, oncologists should be alert to epiphora and cooperate with ophthalmologists in the early stages to improve the quality of life of patients and avoid more complicated ophthalmologic procedures.

    ABSTRACT: PREFACE: The first edition of the General Rules for Gastric Cancer Study was published by the Japanese Research Society for Gastric Cancer (JRSGC) in 1963. The first English edition [1] was based on the 12th Japanese edition and was published in 1995. In 1997, the JRSGC was transformed into the Japanese Gastric Cancer Association and this new association has maintained its commitment to the concept of the Japanese Classification. This second English edition was based on the 13th Japanese edition [2].The aim of this classification is to provide a common language for the clinical and pathological description of gastric cancer and thereby contribute to continued research and improvements in treatment and diagnosis.

    ABSTRACT: To determine the prevalence of tearing and canalicular fibrosis in patients receiving systemic 5-fluorouracil (5-FU) therapy and the reversibility of the symptoms when treatment is stopped. Prospective study. University-affiliated tertiary care hospital in Toronto. Thirty patients (17 men and 13 women aged 38 to 81 years) with advanced gastrointestinal carcinoma receiving intravenous 5-FU therapy as palliative (weekly) treatment (20 patients) or adjunctive (cycle) treatment (10 patients). Tearing, eyelid changes and canalicular fibrosis during and after treatment. Patients who experienced tearing were advised to massage and wipe the lower eyelids in an upward direction. Tearing and canalicular fibrosis developed in 10 patients (50%) and 3 patients (15%) respectively in the palliative treatment group; no patient in the adjunctive treatment group experienced these side effects. In the palliative treatment group, the patients who experienced tearing received double the dose of 5-FU (p = 0.03) and received treatment for twice as long (p = 0.042) as those who did not experience tearing. Of the patients with tearing, those in whom canalicular fibrosis developed received treatment for three times as long as those without fibrosis and received 2.6 times the total dose (p < 0.000). Of the seven patients with tearing in whom canalicular fibrosis did not develop, four stopped 5-FU treatment, and 2 to 4 weeks later the epiphora disappeared. Our findings suggest that the prevalence of tearing and canalicular fibrosis in patients receiving systemic 5-FU therapy as palliative treatment is related to the total dose and duration of treatment. Such side effects are less likely in those receiving adjunctive therapy. The epiphora is often reversible on stopping therapy if canalicular fibrosis has not yet developed.

    ABSTRACT: Ocular toxicity is a common, but poorly understood, sequela from CMF chemotherapy. We investigated this toxicity in patients receiving CMF therapy. Detailed interviews in 210 patients revealed that new, unpleasant ocular symptoms developed in 42% of patients receiving CMF, in 39% of subjects receiving other regimens containing 5-fluorouracil (5-FU), and only in 18% of subjects receiving a variety of chemotherapy regimens not containing 5-FU. CMF-associated ocular symptoms usually consisted of mild to marked tearing, ocular pruritus, and/or burning. These toxicities usually began 11-17 days after starting a cycle of CMF and lasted for 10-15 days. 5-FU was detected in the tears of 12 tested patients within several minutes after intravenous 5-FU (peak concentrations as high as 60 micrograms/ml). 5-FU tear concentrations did not correlate with the presence or absence of ocular toxicity. There is no established antidote for this toxicity although some patients have reported subjective benefit from cryotherapy, applied around the period of 5-FU injections, or cromolyn sodium eye drops.
