Cancer incorrects Flashcards
in people aged 60 and over with hypercalcaemia or leukopenia and a presentation that is consistent with possible myeloma eg back pain, what is the first line investigation?
serum electrophoresis
27 year old with 2 cm mobile breast lump. no other findings. management?
routine!!! breast clinic referral
NICE CKS recommends a 2-week-wait referral for those AGED 30!!! or over with an unexplained breast lump,
OR over 50 years old with unilateral nipple changes.
which type of hodgkins lymphoma carry the best and worst prognosis?
most common type?
best = lymphocyte rich
worst = lymphocyte predominant
most common = nodular sclerosing
which type of lung cancer can cause cushings syndrome?
Small cell!!
can also secrete adh and can cause lambert eaton syndrome
small cell but make you SADh
small cell cancer but it makes you
describe paraneoplastic syndromes associates with squamous cell lung cancer
what about associated with adenocarcinomas?
hypercalcaemia
hypertrophic pulmonary osteoarthropathy (HPOA)
hyperthyroidism due to ectopic TSH
gynaecomastia
hypertrophic pulmonary osteoarthropathy (HPOA)
side effect of anastrazole use for breast cancer?
osteoporosis -> dexa scan recommended when initiating treatment
how to differentiate AML and CML
CML
=an increase in granulocytes at different stages of maturation +/- thrombocytosis
AML - neutropenia and thrombocytopenia
Rain drop skull is seen on skull x ray in which condition?
Multiple myeloma
Risk factors for non Hodgkin’s lymphoma?
Caucasians - notttt Afro Caribbean!
History of viral infection (specifically Epstein-Barr virus)
Immune deficiency eg HIV!!,
Testicular cancer is typically seen in which age range
15 and 35 years.
First line investigation for suspected bladder cancer?
Bladder cancer symptoms?
Flexible cystoscopy!
In bladder cancer most present with painless gross hematuria. Small percentage present with microscopic hematuria and infection should be excluded
Tb may present with cough weight loss night sweats
Lung cancer may have history of smoking, CXR could show a central mass
How could lung abscess present?
Lung abscess - fever, foul smelling sputum.!! Risk factors -dysphagia or altered consciousness levels. Typically follows aspiration pneumonia
Tb
Voice hoarseness. 2 months. Ent found no cause. History of smoking. Cxr clear.
What investigation is likely to be diagnostic
CT chest - pancoast tumour
Prior to surgery, how is axillary lymphadebopathy assessed? And what is the management if lymphadenopathy is or is not noted?
women with no palpable axillary lymphadenopathy at presentation should have a pre-operative axillary ultrasound before their primary surgery
if negative then they should have a sentinel node biopsy to assess the nodal burden
in patients with breast cancer who present with clinically palpable lymphadenopathy, axillary node clearance is indicated at primary surgery.
this may lead to arm lymphedema and functional arm impairment
(if impossible then axillary radiotherapy)
Essentially you’d always do a lymph node biopsy or node clearance
Indications for mastectomy vs wide local excision?
,Mastectomy = multi focal, = al, central, large lesion in small breast, DCIS > 4 cm
Wide local excision = solitary lesion, peripheral tumour, small lesion in large breast. DCIS less than 4
What hormonal therapy is added on in ER positive breast cancers in pre and post menopausal women?
Pre or peri = tamoxifen
Post = anastrozole
What biological therapy is used in HER 2 positive breast cancers?
Trastuzumab
When is chemotherapy used to treat breast cancer?
neo-adjuvant to downgrade primary tumours before surgery or when there is axillary node disease found.
A 56-year-old woman is diagnosed with left breast cancer and undergoes wide local excision with sentinel node biopsy. The sentinel node is negative for cancerous cells.
What would be the next step in management?
Whole breast radiotherapy!!
It is recommending after wide local excision
No chemo needed as no lymph node involvement
bladder cancer treatment?
in situ = transurethral resection of superficial lesions
invasive = radical cystectomy or radical radiotherapy
hypercalcemia effect on QT interval?
shortens
what is the first line *imaging in multiple myeloma?
whole body MRI
A 73-year-old male with a background history of prostate cancer treated by external beam radiation therapy 5 years ago presents with a 3-month history of urgency, diarrhoea, and crampy abdominal pain.
On examination, the patient appears thin with conjunctival pallor. The abdomen is soft and non-tender, with no blood or mucus on digital rectal examination. most likely diagnosis?
colorectal cancer
patients may develop proctitis ( inflammation of the rectum bloody diarrhoea, tenesmus, and painful diarrhoea) and are also at increased risk of bladder, colon, and rectal cancer following radiotherapy for prostate cancer
diagnostic investigation for pancreatic cancer?
name the sign that may be seen
CT pancreas
double duct sign
palpable gallbladder
66 yo man presenting with dysphagia to solids and liquids. most important 1st line test?
Upper GI endoscopy within 2 weeks! to rule out oesophageal cancer
(if cancer then you then do endoscopic ultrasound for staging)
*check out your oncology flashcards from last year + do remaining 6 qs on passmed
in lung ccancer what finding may be seen on blood tests
raised platelets
what may interfere with PSA level in a test?
ejaculation or vigorous exercise in last 48 hours
urinary retention NOT constipation
prostatitis and urinary tract infection
small cell lung cancer manaegement?
chemo + radiotherapy
surgery only considered for up to T2N0M0
HNPCC is associated with increased risk of what cancer in a man? , aside from colorectal cancer
pancreatic cancer
