Neoplasia Clincial Conditions Flashcards
what are polyps
mass growing out of the mucosa of the gut which are benign
how do colorectal carcinomas present
rectal bleeding due to ulceration, vomiting, bloating
what is the appearance of a colorectal carcinoma
irregular outline, red, flat, ulcerative
what is used to stage colorectal carcinomas
Dukes staging - looking at how far through the bowel wall it has spread
what are the tumour markers for colorectal carcinomas
CA 19-9, carcinoembryonic antigen
what is the screening program for colorectal carcinoma
blood testing the stool
which screening programs are available in the UK
bowel, breast and cervical
what is the common name of uterine leiomyomatas
fibroid tumours
how do fibroid tumours present
occluding the uterus is painful, pain also from bladder compression or from necrosis of the tumour if it becomes too big
what is the appearance of fibroid tumours
smooth white tumours made of elongated, spindle shaped smooth muscle cells
how does an osteosarcoma present
pain on exertion due to increased blood demand as tumour impinges on blood flow
true or false ovarian teratomas are malignant
false - they are usually benign
true or false: testicular teratomas are usually malignant
true
what is the appearance of a teratoma
tumour containing different tissue types e.g. glands, hair, teeth, sebum
what is chronic lymphocytic leukaemia
malignancy of B cells originating in the bone marrow
what is a lymphoma
malignancy of B cells originating in the lymph nodes
how does a patient with leukaemia present
tired, breathless, lymphadenopathy, hepatomegaly, splenomegaly, pale conjunctiva
why do leukaemia patients have pale conjunctiva
the bone marrow is producing more WBCs and so less RBCs
why do you get hepatomegaly and splenomegaly in leukaemia
due to an increase break down of malignant blood cells and RBCs as well as extra medullary haemopoiesis
what is the predisposing factor to malignant melanoma
UV exposure
where may a malignant melanoma spread
the brain, lung and liver
where can malignant melanomas also occur
retina
what is the appearance of a malignant melanoma
melanin in the tumour and lymph nodes
what is the appearance of basal cell carcinomas
retraction from the edge of the tissue
true or false BCCs are usually malignant
false
what are the complications of pancreatic adenocarcinomas
DVTs as adenocarcinomas produce mucins which are hypercoaguable
why do patients get jaundice with pancreatic adenocarcinomas
as the tumour blocks the bile duct
what symptoms are seen with a neuroendocrine tumour
abdominal pain, sweating and flushing
what is a neuroendocrine tumour commonly called
carcinoid tumour
why causes the symptoms seen in a carcinoid tumour
the production of serotonin (5HT)
what are the complications of a carcinoid tumour
liver metastases due to first pass metabolism which then spread to stomach - if they are only in the liver you would get no symptoms as the liver will break down the serotonin
what causes Burkitt’s lymphoma
EBV virus as it prevents B cells undergoing apoptosis so they continue to proliferate and become malignant
