Kort sagt

Lymphoma is a common and treatable cancer of the immune system in dogs and cats. Originating in solid organs like the lymph nodes, spleen, or intestines, it presents in several distinct forms. Learn how to recognize the signs, what diagnostic tests your vet will perform, and how modern chemotherapy protocols can extend your pet's life while preserving their daily quality of life.

TL;DR. Vanlig lymfocytcancer i solida organ; ofta svullna lymfknutor eller kroniska mag-tarmproblem; svarar val pa cytostatika.

Ofta smärtfri svullnad av perifera lymfknutor.

Vad ar det?

Malign lymfocytsjukdom fran solida organ (lymfknutor, lever, mjalte, oga), skiljd fran lymfoid leukemi fran benmargen. Former: multicentrisk (hund vanlig), alimentär (katt vanlig), mediastinal, extranodal (hud, oga, njure, CNS).

Orsaker och riskfaktorer

Multifaktoriell. Katt: FeLV/FIV-koppling. Miljo (rok, bekämpningsmedel) misstankt. Medelalders till aldre.

Tecken

Lymfadenopati (kardinal, multicentrisk)
Letargi, dyspne/hosta, viktnedgang, anorexi, krakningar/diarre (vanliga)
PU/PD (hyperkalcemi), ogon-/hudforandringar, nysningar, neurotecken (ibland)

Okulara forandringar som uveit kan folja med.

Diagnostik

FNA-cytologi, biopsi (guldstandard), ultraljud (tarmvagg), staging (blodstatus, kemi, FeLV/FIV, rontgen/UL), immunfenotyp (flow/PARR).

Ultrasound monitor showing a thickened intestinal wall in a cat.
Ultraljud visar typisk tarmvaggsfortjockning vid alimentärt lymfom.

Behandling

Systemiskt: multiagent CHOP/CEOP (referens); COP Protocol som alternativ; rescue Lomustine, Cytarabine (CNS). Mal: livskvalitet och remission.

Prognos

Obehandlad: ~4–8 veckor. Hund CHOP: ~80–90% remission, ~12–16 manader. Katt CHOP: ~65–75%, ~6–9 manader. Small-cell intestinal (katt): ofta >2 ar.

Forebyggande

Katt: inomhus, FeLV-skydd. Mindre rok/bekämpningsmedel. Kontroller av seniors.

Nar du ska ringa veterinaren

Akut: andnod, plotslig blindhet, kollaps, kvarstaende krakningar/diarre, ansiktsödem, feber/hypotermi.
