    Aim: Due to the common etiologic factor, a considerable number of esophagogastric cancer patients suffer from respiratory insufficiency in course of chronic obstructive pulmonary disease, primary to cancer. Systemic hypoxemia may account for poor oxygenation of tumor tissue-a main driving force of tumor neoangiogenesis. We hypothesized that in cancer patients with respiratory insufficiency, systemic hypoxemia may be related to enhanced aggressiveness of cancer on one side and to the elevation of angiogenic factors on the other. Methods: The levels of vascular endothelial growth factors A and C were determined with immunoenzymatic methods in patients diagnosed with esophagogastric cancer with or without co-existing respiratory insufficiency in course of chronic obstructive pulmonary disease and in healthy controls. Blood gasometry and hemoglobin levels of cancer patients were related to cancer histology and TNM status, and to circulating vascular endothelial growth factors A and C. Results: Patients with systemic hypoxemia had higher incidence rates of locally advanced tumors. Partial oxygen pressure and blood oxygen saturation were significantly lowered in patients with T4 cancers as compared to less advanced onces. Circulating vascular endothelial growth factor A, but not C, was more elevated in esophagogastric cancer patients with co-existing respiratory insufficiency, as compared to those without respiratory insufficiency. Vascular endothelial growth factor A was also strongly related to the extension of primary tumor. Conclusion: Our results show that systemic hypoxemia in esophagogastric cancer patients is associated with the extension of primary tumor and that this effect might be mediated by the up-regulation of circulating vascular endothelial growth factor A.ЦСль: Π² связи с ΠΎΠ±Ρ‰ΠΈΠΌ этиологичСским Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠΌ заболСвания , Π·Π½Π°Ρ‡ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ΅ количСство Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Π³Π°ΡΡ‚Ρ€ΠΎΡΠ·ΠΎΡ„Π°Π³Π°Π»ΡŒΠ½Ρ‹ΠΌ Ρ€Π°ΠΊΠΎΠΌ страдаСт ΠΎΡ‚ рСспираторной нСдостаточности Π² процСссС хроничСского обструктивного Π»Π΅Π³ΠΎΡ‡Π½ΠΎΠ³ΠΎ заболСвания, ΠΊΠΎΡ‚ΠΎ- Ρ€ΠΎΠ΅ ΠΏΡ€Π΅Π΄ΡˆΠ΅ΡΡ‚Π²ΡƒΠ΅Ρ‚ Ρ€Π°ΠΊΡƒ.

    A number of esophageal cancer patients suffer from respiratory insufficiency due to the coexistence of chronic obstructive pulmonary disease (COPD). Aim: To test the hypothesis that COPD-related systemic hypoxemia may result in accelerated inflammation, malnutrition, and angiogenesis in esophageal cancer patients. Methods: Serum levels of C-reactive protein (CRP), albumin, transferrin, interleukin-1, interleukin-6, interleukin-8, TNF- a, platelet-derived growth factor (PDGF-BB), and midkine and patient BMI and weight-loss rate were determined and compared with blood oxygenation status (pO2, SaO2) in 35 esophageal cancer patients and 42 controls. Results: The incidence of cachexia tended to be higher in patients with systemic hypoxemia (67% vs 40%, p = 0.169). Mean SaO2 level was also significantly decreased in cachectic patients (90.3 vs 93.3%, p = 0.026) and pO2 exhibited a similar trend (58.0 vs 63.4 mmHg, p = 0.120). Transferrin (234 vs 316 mg/dl, p = 0.005) and albumin (31.9 vs 37.1 mg/dl, p = 0.002) concentrations were reduced and CRP was elevated (129.9 vs 54.7 mg/l, p = 0.004) in hypoxemic patients and correlated with pO2 (r = 0.47, p = 0.016; r = 0.48, p = 0.012; r = –0.37, p = 0.064) and SaO2 (r = 0.52, p = 0.006; r = 0.53, p = 0.006; r = –0.40, p = 0.042). Interleukin-6 (9.97 vs 2.21 pg/ml, p = 0.005) and midkine (2101 vs 944 pg/ml, p < 0.001) were elevated and PDGF-BB was decreased (12.2 vs 17.3 pg x 10-6/PLT, p = 0.014) in hypoxemic compared with normoxemic patients. Interleukin-6 and midkine negatively correlated with pO2 (r = –0.44, p = 0.016; r = –0.42, p = 0.011) and SaO2 (r = –0.54, p = 0.003; r = –0.57, p < 0.0001) and PDGF-BB correlated positively (r = 0.53, p = 0.003; r = 0.44, p = 0.020). Interleukin-8 level was affected by pO2 (r = -0.55, p = 0.015) and SaO2 (r = –0.55, p = 0.018) only in hypoxemic patients. Conclusions: COPD-related systemic hypoxemia negatively affects the status of esophageal cancer patients by accelerating inflammation, under-nutrition, and angiogenesis.МногиС Π±ΠΎΠ»ΡŒΠ½Ρ‹Π΅ Ρ€Π°ΠΊΠΎΠΌ ΠΏΠΈΡ‰Π΅Π²ΠΎΠ΄Π° ΡΡ‚Ρ€Π°Π΄Π°ΡŽΡ‚ ΠΎΡ‚ рСспираторной нСдостаточности ΠΈΠ·-Π·Π° развития хроничСского обструктивного Π»Π΅Π³ΠΎΡ‡Π½ΠΎΠ³ΠΎ заболСвания (COPD).
