A 2-week pretreatment with 13-cis-retinoic acid + interferon-α-2a prior to definitive radiation improves tumor tissue oxygenation in cervical cancers

Abstract: Pretreatment with cRA/IFN improves oxygenation of primarily hypoxic cervical cancers. The mechanisms of action remain unclear and further investigation of the combination regimen is recommended.

“…The Eppendorf histograph directly measuring the intratumoral pO 2 has been used in clinical studies since the late 1980s in human cervical carcinomas [11-13, 17, 18, 22, 25, 27, 31, 36, 37, 39]. Our own results that examined changes in median pO 2 values among patients undergoing radiation therapy for advanced cervical cancer indicated that pO 2 level was an adverse prognostic factor for local control, but only in cases in which hypoxia was sustained after a 2-week course of irradiation (19.8 Gy) [8,9,14]. The measurement with oxygen electrodes has the critical disadvantages of an invasive procedure and is restricted to a few accessible tumors.…”

“…Ein aus strahlentherapeutischer Sicht besonders interessanter Aspekt ist die potentielle Verbesserung der Tumoroxygenierung durch IFN-α/RA [18,19]. Die initialen Daten bezüglich dieses Endpunkts bestätigten sich in einer anschließenden randomisierten Studie (Haensgen & Dunst, Manuskript in Vorbereitung), ohne sich jedoch bisher eindeutig im klinischen Ergebnis niederzuschlagen (Haensgen & Dunst, persönliche Mitteilung).…”

“…Bei 26 Arbeiten (19%; 12%-27%) werden zum Teil Konfidenzintervalle gezeigt, jedoch nicht bei allen Ergebnissen und Grafiken [13, 17, 22, 31, 35, 56, 61, 70-72, 74, 78, 89, 101, 103, 108, 109, 112, 126, 131, 140, 160, 169, 170, 178, 179). Bei 15 Arbeiten (11%; 6%-18%) werden zwar Konfidenzintervalle gezeigt, es wird jedoch nicht immer eindeutig angegeben, um welches Konfidenzintervall es sich dabei handelt [43,45,48,49,60,61,76,86,93,96,135,138,154,155,157].…”

“…In zehn Publikationen (7%; 3%-13%) werden Konfidenzintervalle falsch benutzt, beispielsweise bei der Beschreibung der Altersstruktur der Patienten, etwa in der Form: "Das Durchschnittsalter der Patienten betrug 64 ± 11 Jahre" [17,43,67,74,86,93,101,104,140,163]. Hier ist die Angabe der Spannweite angezeigt.…”
